In the last few years, we’ve seen a lot more movies that take a more honest look at love in all its complexities, rather than the fairytales that have usually been handed to us wrapped up in a perfect bow. The latest in this new let’s-be-honest-about-how-weird-relationships-are-for-once trend is Between Us, a film from Mexican director Rafael Palacio Illingworth.

Superstore’s Ben Feldman and Olivia Thirlby play a couple who’ve been going strong for six years — so strong, in fact, that they decide to just go ahead and get married. Why not? As soon as they make the decision, things get real complicated. It’s as if, by saying out loud that they want to spend the rest of their lives together, they’ve invited the universe to throw everything it can at them to convince them they made the wrong choice. Marriage is a daunting prospect, no matter how in love you are. How do these two know if, in six more years’ time, they’ll want to stay together as much as they did before?

A long-term relationship threatens to implode over the course of one tumultuous night. After six years together, thirty-something couple Henry (Ben Feldman) and Dianne (Olivia Thirlby) find themselves caught between their fears of commitment and societal pressure to settle down and marry. An impulsive decision and a surprise revelation send each into an emotional tailspin. Heading out into the LA night, both Henry and Dianne encounter strangers—he a free-spirited rocker (Adam Goldberg), she a charming artist (Analeigh Tipton)—who offer the possibility of new romantic thrills. The choices each makes will determine what—if anything—will be left of their relationship come morning. By turns brutally honest and incisively funny, Between Us is a raw, real, and all-too-relatable look at the rocky terrain of 21st century romance.

Between Us opens in theaters and On Demand January 6, 2017.
