Plot
Barry Nichols, Joy Henderson, Sybil Wren, and Angèle Ducros were formerly members of the cabaret dance troupe Barry Nichols and Les Girls. Years after the group has dissolved, Sybil, now Lady Wren, publishes a tell-all memoir recounting her days with the troupe, which includes a chapter detailing Angèle's alleged suicide attempt after Barry ended their affair. Angèle, now married to French businessman Pierre Ducros, is outraged by Sybil's claims and sues her for libel. The case goes to trial at the Royal Courts of Justice in London, where the two women relate the history of the troupe as they recall it.
Sybil is the first to take the stand and present her side of the story: In 1949, after Barry hired Angèle as the third principal dancer, she moved in with Sybil and Joy in their apartment in Paris. Unbeknownst to Barry, Angèle was engaged to a young man named Pierre, who knew nothing of the troupe. Angèle and Barry soon began an affair, and while they were out one night, Pierre arrived at the apartment to surprise his fiancée, leaving Sybil and Joy to cover for Angèle.
The following night, during one of the troupe's performances, Joy claimed to notice Pierre and his parents in the audience, causing Angèle to fumble through the rest of the performance and leave the stage prematurely. When Angèle failed to show up for a subsequent number with Barry, thus humiliating him, he angrily fired her, which left her devastated. Later that night, Sybil returned to the apartment and found Angèle unconscious from inhaling gas.
The next day in court, Angèle relates her version of the events: After discovering Sybil's drinking problem, Barry threatened to fire her until Angèle convinced him that Sybil drank because she was secretly in love with him. Sympathetic, Barry helped Sybil achieve sobriety and the two began an affair. While the troupe were on a European tour, Sybil was surprised by her fiancé, English businessman Gerald Wren, in Granada. Gerald offered Barry his own theater for the troupe, hoping Sybil will return to London.
That night at a flamenco club, upon learning of Sybil's affair with Barry, Gerald started a physical altercation with him. Later, Sybil attempted to apologize to Barry, who declared that he only became involved with her out of pity for her alcoholism. Back in Paris, Sybil relapsed into alcoholism and was fired by Barry after performing drunkenly on opening night. Returning to the apartment later that night, Angèle found Sybil unconscious from inhaling gas.
Finally, Barry takes the stand to reveal that neither of the women's stories were accurate: All along, Barry had actually been pursuing the shy and wholesome Joy romantically. Pierre and Gerald asked Barry to fire Angèle and Sybil so they could marry the women. Instead of firing the women, Barry faked a heart condition to gain Joy's sympathy. The three women, distraught at the sudden news, all agreed to quit for his sake. After the women threw a farewell party for Barry, Joy rejected his advances out of concern for his heart, so he admitted to the ruse. Joy stormed out of Barry's apartment in anger, and he ran after her.
Arriving at the women's apartment, Barry found Sybil and Angèle unconscious, both having accidentally been exposed to the toxic gas due to a faulty heater. After both women were hospitalized, they never saw each other again until the trial, marking the end of Les Girls. With the case now settled that there was no suicide attempt, but rather both women had misunderstood the gas leak as a suicide attempt on behalf of the other, Sybil and Angèle reunite outside the courthouse to make amends. As Barry leaves with Joy, who is now his wife, she voices her suspicion that Sybil and Angèle did not completely invent their relationships with Barry.
