Cristin Milioti and Andy Samberg in Palm Springs. | Chris Willard/Sundance Institute

Starring Andy Samberg and Cristin Milioti, the movie broke records when it was acquired at Sundance for $17.5 million … and 69 cents.

Nyles (Andy Samberg) is a nihilistic dirtbag stuck in Palm Springs for a wedding he really, really doesn’t want to attend, with a girlfriend he really, really doesn’t like. Sarah (Cristin Milioti) is the bride’s sister and maid of honor — and she wants to be there even less. They’re both frustrated screw-ups, unhappy with life and love, and thus naturally drawn to one another.

But when they break away from the wedding for a tryst out in the desert, something goes very wrong, and they find themselves stuck with one another in a way neither expected. Nyles’s lackadaisical, nothing-matters attitude seems like the only way to survive. But maybe there are life lessons to be learned here.
