In her new film, Your Sister’s Sister, Sundance award-winning filmmaker Lynn Shelton explores the complexities of interpersonal relationships with off-the-cuff humor and intimate authenticity.

Mark Duplass (Safety Not Guaranteed, The League) stars as Jack who, a year after his brother’s death, is still emotionally struggling and lost in life. He takes up an offer from his friend (and dead brother’s ex-girlfriend) Iris (Emily Blunt) to stay at her father’s isolated cabin to seek comfort and catharsis in solitude.

Upon arriving at the cabin, Jack meets Iris’ sister Hannah (Rosemarie DeWitt), who is reeling from the abrupt end of a seven-year relationship. The two bond over a long night of drinking and swapping stories, a sequence entirely improvised by Duplass and DeWitt. As it usually does, the drinking leads to spontaneous, casual sex – which triggers a complicated, really awkward love triangle when Iris arrives for a surprise visit.
