A man attending a business conference desperately tries to hook up with someone but repeatedly humiliates himself.

A couple stays up all night having a candid and sober heart-to-heart about their past infidelities, which permanently changes their relationship.

The anthology features several standalone stories directed by different filmmakers:

Fred and Greg are seen roaming the clubs of Paris, seducing women, and using hotels to hide their flings from their wives.

Rather than one linear narrative, the film follows two primary characters, Fred (played by Jean Dujardin) and Greg (played by Gilles Lellouche), who serve as the recurring "serial cheaters".
