Sara plans a Christmas party with ex-husbands, current husband Janne, and their families. Booze flows, guests fight and mention sex with Sara. She shockingly announces pregnancy despite Janne's vasectomy. The party descends into chaos.

In what MUST be one of the WORST ideas in Christmas-party-planning history, Swedish homemaker Sara decides to celebrate the Yuletide season with her three ex-husbands and their families. Her current spouse Janne is initially quite opposed but eventually gives in. Then the booze kicks in. Families start in-fighting. Janne grows more and more annoyed as the guests keep referring to having sex with his wife. And during dinner, Sara announces she is pregnant--quite the surprise for Janne, who had a vasectomy the year before. Soon the party devolves into utter chaos.
