IFC Films has released the first trailer for Your Sister's Sister, which is set to hit theaters nationwide June 15. Emily Blunt, Rosemarie DeWitt, and Mark Duplass star in this dramatic comedy about a man who complicates his life by sleeping with his friend's sister.A year after his brother Tom's death, Jack (Duplass) is an emotionally unstable slacker. When he makes a scene at a memorial party, Tom's ex-girlfriend 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, a lesbian reeling from the abrupt end of a seven-year relationship who finds solace in the affable Tom's unexpected presence, and the two bond over a long night of drinking. The blurry evening concludes with an awkward sexual incident made worse by Iris' sudden presence at the cabin the next morning which sets into motion a twisted tale of ever-complicated relationships.
