Jack (Mark Duplass) is still mourning the death of his brother a year later and struggling to get his life on track. His best friend and an ex of his late sibling, Iris (a charming Emily Blunt) intervenes and sends Jack to her family's holiday pad in the San Juan Islands, outside of Seattle, for a little solo R and R. But Jack is unexpectedly welcomed by Iris' sister Hanna (the ever-brilliant Rosemarie Dewitt), who has recently retreated to the house to mend her wounds over a recent breakup… using shots of tequila. Jack joins in and a one-night stand ensues, but the fit really hits the shan the next morning when Iris shows up unannounced.
