Lars (Aksel Hennie) and Lisa (Noomi Rapace) have lost much of the love that brought them together in the first place. Now, they're struggling to maintain their marriage, and their ambitions. Lars' career as a director has stalled out in soap operas, and Lisa hasn't landed a part in years. Lars feels ignored, suspects he's being cheated on, and struggles financially. Lisa thinks Lars is a spoiled, self-centered coward.
Nothing about their lives turned out the way they'd thought it would – their marriage least of all. So a weekend trip to the family cabin in the woods seems to offer them both an opportunity to get rid of the other. Permanently.
But not even this goes according to plan. The trip involves more surprises and unforeseen turns of events than they'd imagined.
