Hip talk-radio host and journalist Mingus (Chris Rock) and his French photographer girlfriend, Marion (Julie Delpy), live cozily in a New York apartment with their cat and two young children from previous relationships. But when Marion's jolly father (played by Delpy's real-life dad, Albert Delpy), her oversexed sister, and her sister's outrageous boyfriend unceremoniously descend upon them for an overseas visit, it initiates two unforgettable days of family mayhem.

With their unabashed openness and sexual frankness, the triumvirate is bereft of boundaries or filters... and no one is left unscathed in its wake. The visitors push every button in the couple's relationship, truly putting it to the test. How will the couple fare... when the French come to New York?
