Tree planters Quinn and Rosa return to camp for another summer in the wilderness. Rosa is newly sober, and Quinn is quietly anxious about how she’ll handle the camp’s hard-partying culture. At the welcome-back party, Rosa is tempted to drink, prompting Quinn to intervene. Shaken, Rosa heads into the forest to clear her head, but doesn’t come back. When Quinn goes after her, she’s met with eerie signs: strange noises, a mangled deer, and an odd light deep in the woods. As the forest closes in, Quinn questions if there is something else out there.
