Written and directed by Korstiaan Vandiver, the film ‘Gym Rat’ centers on Lonnie Milsap, a fitness-obsessed ex-convict freshly released from prison and chasing a dream of becoming the next Mr. Olympia. Struggling to rebuild his life, he takes a job selling steroids for a volatile gym owner and spirals into drugs, violence, and self-destruction. Haunted by his lifelong idol Lou Ferrigno — who appears as both himself and a projection of the man Lonnie wants to become — Lonnie unravels as obsession and illegal steroids collide, until love forces him to confront the monster within.
