As a child, Wyatt witnessed a group of peaceful aliens survive the military's attempt at mass extermination. Ever since, he's taken a sympathetic interest in the aliens and exhibited a particular fascination with their young queen. Now an adult, Wyatt (Tim O'Leary) works as the police chief in the small town of Elm Grove and protects the stranded aliens by hiding them inside a complex of local caverns. Wyatt's new partner, Lucas (Chad Crenshaw), seeks an escape from the troubles of his previous job, where he was fired and accused of cowardice, but soon after his arrival, Elm Grove proves anything but the sleepy burg of his hopes. Unable to reproduce and facing extinction, the ETs abandon their pacifist ways, initiating a deadly fight for survival. Their violent betrayal of Wyatt's long-term kindness turns both his threatened town and his benign view of the aliens upside-down.
