“A year after his brother’s death, Jack (Mark Duplass) still see-saws between emotionally wobbly and outright volatile. When he makes a scene at a memorial party, Iris (Emily Blunt) intervenes with a plan: Jack must oil up his old bike and trek to her father’s cabin on an island on Puget Sound, where isolation will give his brain a chance to detangle. When Jack gets to the woods, however, he finds not solitude but Iris’ sister Hannah (Rosemarie DeWitt), herself nursing a wounded heart and a bottle of tequila. After several shots and some slurred commiseration, liquor isn’t the only fluid these two end up sharing. Their hangover descends in the form of Iris, who pulls up with a bag of groceries the next morning. Though ripe for love-triangle trappings, Your Sister’s Sister offers an uncontrived navigation of romantic and sibling relationships. Shelton’s perceptive script proves that intimate films don’t have to be small; in fact, it is the characters’ sense of closeness that produces large-scale emotional resonances. Its humour may swing from understated to raunchy, but Your Sister’s Sister is always smart”—Toronto Film Festival. R. 90 Min.
