It stars Rami Malek, DJ Qualls, Kate Lyn Sheil, Lin Shaye, Toby Huss, Sukha Belle Potter, Lily Gladstone, and Nicholas Pryor.

An eccentric mountain man is on the run from the authorities, surviving the winter by breaking into empty vacation homes in a remote community.

Regularly calling into radio talk shows — where he has acquired the nickname "Buster" — to rant about the impending inversion at the turn of the millennium, he is haunted by visions of being lost at sea, and memories of his former life as a family man.

Buster was once Jonah, a husband and father whose job as the night-shift concierge at a hotel took its toll on his psyche and, consequently, his marriage to Marty — until a chance encounter with conspiracy-obsessed drifter Brown changed the course of their lives forever.

[2] Buster's Mal Heart was filmed near Glacier National Park and in Kalispell, MT, as well as on the ocean in open water.

Originally, Smith planned to film in her home-state of Colorado but, in the end, decided to shoot in Montana for the available state grant as well as the unique and dramatic landscape.
