Park City, UT. Leave No Trace premiered at the Sundance Film Festival to critical acclaim. Director Debra Granik adapted the screenplay for the film with her writing partner, Anne Rosellini, from the Peter Rock novel, My Abandonment, which was based on the true story of a father who lived with his teenage daughter in Forest Park for four years.

Here’s a trailer for Leave No Trace:

The film follows the true story of the pair as they inhabit a cave shelter in Forest Park, wash in a nearby creek, store perishables at the water’s edge, use a makeshift septic system, tend a garden, even keep a library of sorts. Once a week they leave their camp to buy groceries and otherwise merge with the civilized world.

Ultimately, a backcountry jogger discovers them, which derails their entire existence, and ultimately provokes a deeper flight.

The North American distribution rights for Leave no Trace were obtained by Bleecker Street and a release date will be announced later this year.
