Body at Brighton Rock

Wendy, a part-time summer employee at a mountainous state park, takes on a rough trail assignment at the end of the season, trying to prove to her friends that she's capable enough to do the job. When she takes a wrong turn and ends up deep in the backcountry, she stumbles upon a potential crime scene. Stuck with no communication after losing her radio and with orders to guard the site, Wendy must fight the urge to run.
