Smart, savvy advertising executive Murray Roberts is in control of his urban world. But a wrong turn in a large metropolitan park reveals the limits of his control as well as his own shortcomings. Murray's path is blocked by Carter, a 14-year-old would-be mugger. When Carter persists, Murray reacts and shoves him to the ground. The act has alarming consequences as a menacing youth gang emerges from the surrounding forest. Murray does the only thing he can think of given the situation: He runs. Cornered and exhausted, he seeks refuge in a massive old tree. A single misstep atop the branches and his hiding place is revealed. Deep in the woods at the end of the day, no one answers when Murray calls for help.
