Grant Grant, the town's wealthiest and most powerful citizen, is taking a walk through the woods when he comes across a strange and unfamiliar life form.

Grant's wife, Starla, begins to notice that something is very wrong with her husband. At the same time, Sheriff Bill Pardy becomes aware that there is a pattern of missing people and animals. Together, Starla and Bill set out to put a stop to the alien invaders intent upon taking over Wheelsy.
