The great friendship of Jack (Mark Duplass) and Iris (Emily Blunt) is tested when Jack visits the remote cabin that belongs to Iris's family, and her sister Hannah (Rosemarie DeWitt) is already there. What's more, Iris shows up the next morning.
To say that the next few days become complicated for the trio would be an understatement as the twists and turns of this entertaining, heart-filled comedy unfold.
Lynn Shelton's YOUR SISTER'S SISTER opened the 38th Annual Seattle International Film Festival.
