One of the more charming movies I’ve seen within the last year is the next film from Humpday director Lynn Shelton. Your Sister’s Sister premiered at TIFF and stars Mark Duplass, Emily Blunt and Rosemarie DeWitt in a sort of love triangle. Shelton brings a naturalistic vibe and expands upon her “mumblecore” beginnings with wonderful conversations amongst our three leads. We’ve got the first trailer today via Yahoo and although it features the soothing sounds of Band of Horses, it actually gives away just about every major plot turn. So, I’d suggest skipping over it and waiting to see it during its theatrical run this summer or Tribeca Film Festival.

Synopsis:

A year after his brother’s death, Jack is still emotionally fragile. When he makes a scene at a memorial party, Iris decides to intervene. She gets Jack to oil up his old bike and drive out to her father’s cabin on an island on Puget Sound, where she hopes he will be able to work through things. When Jack arrives at the cabin, he does not find restorative solitude but instead Iris’ sister Hannah, nursing a wounded heart and a bottle of tequila. After throwing back a few drinks, these two end up getting to know each other a little more intimately. Their hangover wake-up call arrives the next morning in the form of Iris with a bag of groceries in hand.

Your Sister’s Sister hits theaters on June 15th.
