Your Sister's Sister

Desperate to help her good friend Jack through a rough patch, Iris (Emily Blunt) offers him her family's island cabin for some peaceful reflection. But upon his arrival, he's surprised to find Iris' older sister Hannah there working through some issues of her own. The two hit it off quickly, and as the night progresses -- and a lot of tequila goes down -- the clothes come off. To make matters even more complicated, Iris unexpectedly shows up the morning after, setting into motion a story of secrets, romance and sibling rivalry.
