When Oscar, recuperating from a divorce, takes a job as a fire lookout in a remote forest outpost, he unearths a mangled sheet of paper inscribed with a strange set of rules that promise to keep him safe during his watch. Oscar laughs it off as a prank— a bit of light hazing from the other fire lookouts in the area — but when night falls, he discovers that the rules, and the threat they protect against, are all too real.
