Your Sister's Sister Movie Poster 4 of 1

A year after his brother Tom's death, Jack (Duplass) is still struggling emotionally. When he makes ascene at a memorial party, Tom's best friend Iris (Blunt) offers up her family cabin on an island in the Pacific Northwest so Jack can seek catharsis in solitude. Once there, however, he runs into Iris' sister Hannah (Dewitt) who is reeling from the abrupt end of a seven-year relationship and finds solace in Tom's unexpected presence. A blurry evening of drinking concludes with an awkward sexual incident, made worse by Iris' sudden presence at the cabin the next morning.
