Part one (November 1, 1998)
In 1958, Otis Williams, at the time a teenager, is running to meet his friend Elbridge "Al" Bryant at a musical performance by The Cadillacs, where Otis and the singer lock eyes, which he credits as the moment he devoted his life to music. After the concert, Otis and Al go to a barber where they get the Tony Curtis and DA-style process. Later, Otis arrives home for dinner, where his stepfather is angered by his hairstyle and pressures him to go to work at the assembly line instead of going into music, which Otis heatedly rejects. Six months later, Otis, Al and two new band members, are singing on a street corner when they see another group of singers, the Voicemasters, across the street, and are impressed by one singer's bass voice type. The next day after school, Otis spots the singer leaving to walk home, and decides to follow him. The singer sees Otis and begins to run away, thinking him to be a gang member. Otis eventually catches him and introduces himself, finding out that the singer's name is Melvin Franklin, and invites him to join his group, Otis Williams & the Siberians. Melvin agrees, on the condition that his mother approves. After talking to her, Otis convinces Melvin's mother to let him join.
The group, now with five members, are practicing their singing after school one day when they notice a group of girls watching them sing. Upon seeing this, the group follows them while singing "Earth Angel". The girls go their separate ways until one girl, Josephine, remains, and Otis asks her out on a date. The next Saturday, the group are making out with the girls in a milk truck when they hear for their group to come to the radio station, and hastily drive to the station, which turns out to be a run-down apartment. Johnnie May Matthews, the owner of the pirate radio studio in the basement, declares herself their new manager and producer, and also changes their name to Otis Williams and the Distants. In April 1960, the group are waiting to perform at a party where they meet Paul Williams, Eddie Kendricks, singers for The Primes, Diana Ross, lead singer for the Primettes, Smokey Robinson, lead singer of Smokey Robinson & the Miracles, and Berry Gordy, founder and owner of Motown Records. Al arrives late at the party and shows hostility towards Eddie and Paul, while hitting on Diana. The Primes and Primettes perform and the Distants are impressed by their sound. After they perform, Otis and Melvin see Berry Gordy entering the bathroom and follow him. After some talking, Berry gives them a business card to contact him later on. Once the party ends, Johnnie shows up in a new car, bought with the money earned from their record, while also showing off rolls of money. Awestruck, they ask about when they get paid, which angers Johnnie and she immediately fires them, kicks them out of the car and drives away. Al and two other members promptly quit the group, leaving Otis and Melvin as the only two remaining members.
Shortly after, Melvin approaches Otis and tells him that Eddie Kendricks and Paul Williams recently left their own group and are interested in joining them. Otis is reluctant, as he finds them arrogant and cocky, but ultimately accepts when Al rejoins the group. With this new line-up, the group renames themselves the Elgins. Paul teaches them how to dance and becomes their unofficial choreographer, while Eddie becomes their falsetto singer. In March 1961, Otis enters Motown Studios, the headquarters of Motown Records, and meets up with Berry Gordy. After the meeting, Otis finds the others waiting outside for an answer. He informs them that Berry will sign them if they can come up with a better group name. After sitting outside the studio for hours waiting to be called in and thinking up a new name, a secretary named Martha Reeves finds them outside and calls them in to meet Berry. When they get to Berry, he asks them for their name, to which Otis replies "The Temptations".
Berry likes the name and agrees to hear them sing. After hearing them perform "Oh Mother of Mine" (which would become their debut single for Motown) Berry enthusiastically signs them under the Motown label. The group are now in high spirits and make a pact to never leave the group. Otis arrives home to find out that Josephine is pregnant, and although he is shocked, he promises to take responsibility for the baby. In a voiceover, Otis explains that he and Josephine were married shortly after and later gave birth to their son, Lamont. While making moderately successful records written largely by Berry, such as "Paradise" and "I Want a Love I Can See", and getting real choreography from Cholly Atkins, the group start to become known as "The Hitless Temptations" in their first three years under the Motown label. The group start to doubt themselves as talented singers and Al starts to lose his passion for singing and becomes more negative and volatile. This comes to a head when, after performing at a New Year's Eve party, Al smashes Paul in the side of the head with a beer bottle when asked to do an encore on stage. He is kicked out the group immediately. The remaining four go back on stage and perform the classic party song "Shout". While singing, Jimmy Ruffin and his younger brother David Ruffin jump on stage and sing as well. The group are impressed with the duo's singing, especially David's. After the party, the four, along with David, go to Melvin's mother's house to eat. While they eat and talk, the four invite David to join, which he readily accepts. With five members once again, they make a toast to the future success of the Temptations.
In January 1964, the group head to Hitsville to record a song written for them by Smokey Robinson, called "The Way You Do the Things You Do", which puts them on the map. Shortly after the song hits the charts, the group go on a tour with various other Motown artists, such as the Vandellas, the Miracles, and Marvin Gaye. One afternoon, while changing a tire on the tour bus, a gang of racist Southerners shoot at them while driving, and David and Eddie try in vain to chase them down, but quickly give up. The tour eventually ends and they all arrive back in Detroit. While Josephine is waiting for Otis in front of Hitsville, she sees him with another woman, and assumes that they are having an affair, and storms off. Soon after, the Temptations go on tour again. In November that year, Smokey writes them another song called "My Girl". The song debuts early the next year and becomes a massive success, reaching number one on the charts that year. The group enjoys their newfound success and wealth, spending money on themselves and their loved ones.
By early 1966, however, David starts to develop an ego, thinking himself to be solely responsible for the Temptations' success. He also begins using drugs and starts showing up late for rehearsals and meetings, if at all. This behavior starts to take a toll on the group, and soon after recording "Ain't Too Proud to Beg", Otis and Melvin pay David a visit, staging an intervention. They warn him to clean up his act or else be fired. Later, Berry introduces the group to their new manager, Shelly Berger. Shelly plans to expand the Temptations' fanbase to the mainstream white audience, which they are somewhat reluctant about, as they think their original fans will see them as sell-outs. After some consideration, the Temptations agree and are put on a month-long tour with the Supremes. The tour turns out to be a success and gets them to the Copacabana, although David's destructive behavior continues, and he declares his shady friend, Flynn, his new manager instead of Shelly. Flynn informs the group that David wants to change their name to "David Ruffin & The Temptations" or else he will not perform, which they reject. David shows up anyway, albeit late, and performs "I'm Losing You" at the Copa, and leaves in a separate limo. After the show, the others take a vote on whether or not they should keep David, and all but Eddie vote to kick him out. Shortly after, David shows up at Hitsville in his limo. While the four watch from a window, Shelly meets David outside and hands him a note informing him of their decision. Upon reading this, David flies into a rage, yelling at them through the window. He then gets into his limo and drives off. Melvin rhetorically asks "So now what"?
Part two (November 2, 1998)
Later in 1968, the Temptations hire Dennis Edwards, an old friend, as a replacement for David. It is around this time that the group enters their psychedelic soul era, started with their 1968 single "Cloud Nine". During a concert performance, the group is about to sing "Ain't Too Proud to Beg" when David jumps on stage and steals the microphone from Dennis and sings himself. The others go along with this to save face, but then chase him backstage afterwards. David and Otis get into a brief argument before getting security guards to escort him out. By 1969, Paul's drinking becomes debilitating, and Melvin develops rheumatoid arthritis in the legs and starts taking cortisone shots to ease the symptoms despite his doctor's advice, yet both continue performing. Around this time Otis and Josephine also get a divorce. As Paul's condition gets progressively worse, the others begin to consider whether Paul should retire, at least for the time being. Eddie is against this. In November 1970, Eddie visits David, who begins to turn him against Otis and Melvin while giving him his first shot of cocaine. Shortly after, Paul becomes well enough to sing again, and the Temptations record a new song written by their producer Norman Whitfield called "Just My Imagination". Eddie quits the group after recording the song. Later, Otis and his son Lamont visit Paul at his house. Paul asks to be back in the Temptations, while demonstrating his dancing, almost falling over. Otis tell him that he will be back when he gets better. In June 1972, Norman writes another song called "Papa Was a Rolling Stone", which the group are initially against recording, but eventually go along with it. In a montage set to the song, Paul is seen struggling with his addiction, while fighting with his wife, and later driving around town, ending with Paul committing suicide in a parking lot. Eddie reunites with the others at the funeral, with Melvin telling him that while he's out of the group, they will always be family.
By 1977, the Temptations have moved from Detroit to Los Angeles and have been hit with a dry spell in their career. The group, now with Otis and Melvin as the only remaining original members, fire Shelly as their manager, leave the Motown label and start recording under the Atlantic Records label. Eddie is still under the Motown label and has made two major hits, while David, who has had some hits after the Temptations, is also under a dry spell. One day, while Melvin is helping a woman with her grocery bags, a thief gets in his car and tries to start it. When Melvin tries to stop him, the thief shoots him in both of his legs, kicks him out, and drives off in his car. Melvin tells Otis to go on tour without him, as they need the money. After the tour, Otis goes back to Detroit with Lamont to visit his mother, who tells him that she has cancer. They then have a heart-to-heart on the porch.
In 1980, Melvin's legs are still recovering and the Temptations leave Atlantic Records. Eddie's success is starting to fade and he is reduced to playing in small nightclubs. While performing one night, Eddie spots David in the audience and once he finishes the song, brings David on stage and they sing together. After everyone leaves the club, Eddie and David have a drink at the bar and agree to start their own faction of the Temptations, along with Dennis Edwards, who was fired from the Temptations in 1978. Otis and Melvin move back to Detroit and go back under the Motown label and Shelly becomes their manager again. Not long after, Motown becomes interested in setting up a reunion tour between both sets of the Temptations.
By 1982, the tour is officially underway and both sets of Temptations come together to rehearse and become reacquainted. While on tour, Josephine calls and informs Otis that Lamont died in a construction accident. After Otis gets back from the funeral, the tour starts to fall apart, as Otis' grief gets the better of him and David's drug addiction starts to trigger his destructive nature.
In 1989, the Temptations are inducted into the Rock and Roll Hall of Fame. At the ceremony, Otis and Melvin are reunited with David, Eddie, and Dennis. Despite their past squabbles and rivalries, for one moment, they are all friends again as they accept their honor and remember Paul.
In June 1991, a dead body is found in front of a hospital. After a week in the morgue, the body is finally identified as that of David Ruffin, dead of an apparent drug overdose. Eddie dies soon after of lung cancer in October 1992.
In February 1995, Otis and Melvin, now in a wheelchair, visit Melvin's mother. While preparing to eat dinner, Melvin, despite being in a wheelchair, volunteers to get short ribs from the kitchen. While he's gone, Melvin's mother thanks Otis for taking care of Melvin and keeping the Temptations together through all the good and bad times. The two then call for Melvin, but he doesn't respond. They go into the kitchen and find him unresponsive. Many people show up at the funeral, including Smokey Robinson, who sings his song "Really Gonna Miss You".
The film ends with the "classic five" Temptations (Otis, Melvin, Eddie, Paul, and David) in their youth, singing "My Girl" on a stage. At the end of the song, they take a bow, with Otis saying in a voice-over "Temptations, forever."
