A year after his brother Tom's death, Jack (Mark Duplass), an emotionally unstable slacker, is offered by Tom's ex-girlfriend Iris (Emily Blunt) to take a vacation at her family cabin in the Pacific Northwest so he can seek catharsis in solitude. Once there, however, Jack runs into Iris' sister Hannah, a lesbian reeling from the abrupt end of a seven-year relationship and who finds solace in the affable Jack's unexpected presence.
