Public Defender Kathy Baker visits the small Florida town of Deep Water to defend a young client being used as a pawn by a politically minded judge. She stumbles onto the town's many peculiarities including a criminally minded backwoods family, an abusive deputy, alligators running rampant, and a crazed environmentalist, all presided over by an eccentric judge, ""Maximum"" Bob Gibbs.

Kathy befriends a dog that saved her life. Meanwhile, the whole town is up in arms over a beast of some sort that attacked a young woman, biting off three fingers. According to witnesses (the Crowe family) the beast was either a Gatorman or the Okeechobee Wolfman. Judge Gibbs hires an exorcist to cast out Wanda Grace.
