French TV star Nagui, described by Variety as "popular for his lowbrow-Letterman approach," portrays Zak, who learns about "the curse of Onan" experienced by males in his family. If Zak does not impregnate a woman before his 33rd birthday, the joys of sex evaporate forever. However, Zak's interest in married women creates a roadblock. Even his current girlfriend, art auctioneer Florence (Cristiana Reali) is a married mother of triplets. So Zak's rabbi cousin Joseph (Thomas Langmann) fixes him up with an attractive supermodel (Joanna Rhodes). It's a race against time before permanent impotence strikes.
