Then, one day, a seemingly minor incident turns their lives upside-down coy, butch lesbian Marijo has car trouble in front of their home, and the friendly Loli invites her in. Laurent, who himself has been cheating on Loli with half the town, immediately accuses the two women of having an affair and, in revenge, reveals his own trespasses. Loli, who never suspected Laurent of infidelity, turns to Marijo for sympathy and comfort. To her surprise, she also discovers her own lesbian desires and soon Marijo and Loli are doing exactly what Laurent accused them of. The love triangle only gets funnier when Laurent tries to win back his happy and sexually satisfied wife.
