Plot
Teenager Kevin has tried to lose his virginity for three years. He and his best friend Perry decide they want to go to Ibiza to become DJs and seduce women. However, when Kevin's parents, Ray and Sheila, see his bad school report, they forbid the trip. They later compromise: the boys can go if they get jobs to pay for it. Searching fruitlessly for jobs, the boys end up at a house party, where a popular girl Sharon passes out drunk next to Kevin. Perry, seeing the two in bed together the following morning, assumes Kevin has lost his virginity. Kevin lies, saying he had sex with Sharon but gets overheard while leaving the party. In the town centre, an angry Sharon confronts and humiliates Kevin about this, mockingly calling him "virgin".
Distraught, Kevin arrives home in time to sign for the delivery of Ray's new credit card. He seizes the card and takes it to the bank to steal the plane fare from Ray's bank account. At the bank, he accidentally foils a robbery, and the manager rewards him and Perry with money with which the boys plan to fund the trip. As a reward, Kevin's parents approve of the trip, as long as they can accompany the boys, much to Kevin's horror.
In Ibiza, the boys spot the 'girls of their dreams' Candice and Gemma. They also meet club DJ and record producer Eyeball Paul. The boys spend the day at the beach and chat with the girls but are unsuccessful in seducing them.
That night, the boys walk filming the events around them. Kevin films a couple snogging, and they turn out to be Ray and Sheila. Kevin sulks while he and Perry hang out with Ray and Sheila, ending up at the club "Amnesia" where they dance the night away—without Candice and Gemma, who were refused entry by the doorman, who holds a hand-mirror to call them ugly.
The next day, the boys go to Paul's, and he makes them clean his house in return for his listening to their tapes. While leaving, they spot Candice and Gemma, but again their attempts to woo them end in failure, although the girls bond with the boys when realising they know Eyeball Paul and they may be able to get them into the clubs.
The boys wait outside the girls' hotel for four hours while the girls have a makeover, and they are admitted to Amnesia with Kevin and Perry, but yet again the boys "strike out" when they get vomited on by other revellers and leave embarrassed while the girls meet two other men in the club. That night, Perry videotapes Ray and Sheila having sex. The next day, Paul listens to the boys' music as they clean his kitchen. He stumbles across the parents' sex tape and shows it to everyone. Kevin lashes out at Perry after realizing that it was Perry who filmed them. Baz, Paul's manager and chauffeur driver, later persuades Paul to give the video back to the boys.
Kevin spends the rest of the day sulking around alone and becomes dejected after seeing the girls with the men from the club. Perry spends the day at the beach and bumps into the girls. The two men who are revealed to be gay lovers who the girls had befriended. Gemma reveals she is attracted to Perry and Candice admits to liking Kevin. Perry then runs into Eyeball Paul, who says he likes their song and he will play it in the club that night. Perry hurries to tell Kevin the news, and the friends reconcile.
That night, they and the girls go to the club again in Paul's limousine. Their track is played, but the boys and Ray and Sheila, who had wanted to visit the club, are embarrassed to find that Paul has incorporated the sex tape and the boy's love messages to the girls into the track in an attempt to humiliate the boys.
This backfires on Paul when the track becomes a club favourite and the crowd, including the girls, love the boys and their mix. Unhappy at the boys' success, Paul turns off the track, which angers the crowd. Paul becomes annoyed and attempts to destroy the boy's vinyl record but is stopped by Baz. Paul fires Baz, who punches and pushes him off stage before returning the record to the boys to continue the set, and the crowd continue to party.
Kevin and Perry take over as DJs and keep the club dancing through the night. The next morning, Kevin and Perry have sex with Candice and Gemma, respectively, on a beach surrounded by other couples having sex.
The girls become the boys' girlfriends while Kevin and Perry sign copies of their record in a music shop with Baz as their new manager. Sharon receives a signed copy of the record and boasts that she and Kevin had sex before he was famous while Kevin's parents sign copies of their videos about better mid-marriage sexual intimacy.
