The Red Citrus trailer park is inhabited mostly by illegal laborers. But the steroid-powered park manager and his grotesquely muscular girlfriend figure that selling the park to developers would be easy money--and they're ready to do whatever it takes to drive the residents out.

The problem is a young girl who the laborers believe talks to God. The manager doesn't know if she's valuable or a liability. But when the girl witnesses him dumping a corpse into a lake, there is one thing he knows for certain: He's got to shut her up permanently.

The girl's only hope for survival: marine biologist Doc Ford, who must search through an underground, invisible nation...and hope he reaches her in time.
