How Can You Be Certain He Is The One, If He Is The Only One?

Anna (Golden Globe nominee Rebecca Hall, Vicky Cristina Barcelona) and Will (Dan Stevens, Beauty and the Beast, Downton Abbey), were each other’s first everythings: first kiss, first love, first and only relationship. Now, 10 years in, at Anna’s 30th birthday party, as Will is about to propose, the couple’s best friend makes a drunken toast, suggesting that they should sleep around before their inevitable marriage. The joke lands like a lead balloon, but the thought lingers until Anna proposes that they try opening their relationship – as a sexual experiment. Together, they venture out of the purely monogamous boundaries of their relationship and, along the way, evolve. Also starring Jason Sudeikis (We’re the Millers).
