Kristen Stewart is no stranger to heartbreak, a fact that she made exceedingly clear in her directorial debut Come Swim.

The successful actress wrote and directed the striking 17-minute short film as part of Refinery29's Shatterbox Anthology film series, and it recently premiered at the Sundance Film Festival to much fanfare. The storyline pulls from the 26-year-old's own relationship experiences and past breakups (though she wouldn't name names, rumors have swirled that Robert Pattinson served as inspiraton), and showcases an emotional day in one man's life (Josh Kaye) as he is overcome and later starved by water.

The piece alternates between abstract representations of his broken heart—like massive waves crashing down on him—and shockingly realistic scenes that feature him trying to get through the workday in a cubicle. The movie also includes snippets of previous conversations between the main character and his ex-girlfriend that he can't seem to get out of his head.

But her former boyfriend and Twilight co-star isn't her only old love linked to the project. The music in the film was scored by St. Vincent, someone Stewart has been romantically involved with in the past.
