Set in the Northern California woods, where residents struggle to fight off repeated attacks from mysterious creatures. When Brock (Sage), a local pot farmer, gets caught up with an unusual group of campers, the situation quickly escalates into total carnage.

With his wife Peggy (Sabina Gadecki), he tries to defend his family and maintain his sanity alongside a ragtag group of misfits including their niece Courtney (Anastasia Baranova), scruffy drifter named Possum (Culkin), a wannabe singer-songwriter Zack (Garrett Clayton), good ol' boy Jeremiah (Chris Zylka), unemployed stoner Klaus (Thomas Dekker), his naive girlfriend (Karrueche Tran) and ditzy sorority girl Cassie (Keelin Woodell).

All the while, Derek (Lundgren), a weathered police officer from Brock's past, haunts him with his partner Jackson (Serge Levin). John Hickman also stars as an ominous convenience store clerk.
