Directed and co-written by Saint Maud‘s Rose Glass, the upcoming movie also stars Dave Franco, Ed Harris, Jena Malone and Anna Baryshnikov in a story that sees two lovers caught in a series of bloody, bullet-filled confrontations.

Stewart stars as reclusive gym manager Lou, who finds herself falling hard for Jackie (O’Brian) after she begins working out at her business.

Jackie is an ambitious bodybuilder who is just headed through town on her way to Vegas in pursuit of her bodybuilding competition dream.

The duo becomes physically and emotionally entangled — not just in their own romance, but in a series of increasingly violent encounters involving Lou’s father (Harris) and a man who works at his shooting range (Franco).

“Looks like you’ve got your hands full,” Anna Baryshnikov’s character says.

Film4 developed the film, co-written by Weronika Tofilska, alongside the filmmakers, with A24 producing with Andrea Cornwell for Lobo Films and Oliver Kassman for Escape Plan Productions.

It is slated to premiere at the 2024 Sundance Film Fest, with a wide release set for March 8, 2024.
