Your Sister's Sister

“A comedy about doing the right thing with the wrong person.”

Jack (Mark Duplass) is still raw a year after his brother's death when his best friend Iris (Emily Blunt) sends him to her family's cabin on an island to clear his head. He arrives to find Hannah (Rosemarie DeWitt), Iris' sister, already there, and a night of tequila puts the two of them in the same room. Lynn Shelton gives Jack little to hold onto beyond grief, and he walks into the weekend with no idea what he wants.
