"Barbara Gold, a retired CIA agent, volunteers to accompany her thirteen-year-old grandson, Martin, on a group camping trip with his peers. Out in the wilderness with no phone coverage, the teens and their guardians are enjoying fresh air and mountain views… until Martin’s photography teacher is found dead in an abandoned mine. Barbara quickly gathers evidence before the rain can wash it away, but she and the campers quickly become the hunted. A psychopath is loose in the woods, tracking their every move. Barbara must use her old spy and combat training to outsmart the killer and keep the kids safe. But doing so might reveal secrets from her past to her beloved grandson."
