LA, 2028. Down-on-their-luck exterminator Sal Hernandez is sick of long hours, living in their work van, and ready to reconcile with their estranged partner. The only thing standing in their way is one last shift. What seems like a routine job is anything but, and when a proselytizing mass of flesh abducts Sal's newest coworker, Luke, an extermination job quickly turns into a rescue mission.

Freshly concussed from a pro-bono job earlier in the morning, for Sal, the line between reality and hallucination begins to blur. Sal and their teammates Molly and Hussam are as experienced as they come, but will it be enough to overcome the horrific creature that waits in the shadows and the incompetence of their boss?
