In Steven Soderbergh‘s Unsane, a young woman is involuntarily committed to a mental institution. She is then confronted by her greatest fear … but is it real or is it a product of her delusion?

A horror film reportedly shot on an iPhone in a single week, this first clip showed Claire Foy having a conversation with a nurse. She explains that she did, in fact, check herself in, but that she’s not insane and wants her one phone call. She tries the police to no avail. Now, here are a handful of images from the home of the possibly insane.

Juno Temple, Jay Pharaoh, Joshua Leonard, Aimee Mullins, and Amy Irving also star.

Bleecker Street will release Unsane on March 23, 2018.
