Hip talk-radio host and journalist Mingus (Chris Rock) and his French photographer girlfriend, Marion (Julie Delpy), live cozily in New York with their cat and two young children from previous relationships. When Marion's jolly father, her oversexed sister, and her sister's lewd boyfriend unceremoniously descends upon them for an overseas visit, it initiates two unforgettable days of family mayhem. How will the couple fare. . . when the French come to New York?

Marion (Julie Delpy) is now settled in New York, where she lives with Mingus (Chris Rock), a radio journalist, their two children from previous relationships and a cat. The couple are very much in love! Marion is still a photographer and preparing her exhibition. Her father, her sister and her boyfriend (who is in fact Marion's ex and who was not planned at all) arrive in New York for the opening. The clash of cultures but above all the unbridled personalities of the three newcomers will cause real fireworks!
