The town psychiatrist has decided to switch everybody in Pine Cove, California, from their normal antidepressants to placebos, so naturally -- well, to be accurate, artificially -- business is booming at the local blues bar. Trouble is, those lonely slide-guitar notes have also attracted a colossal sea beast named Steve with, shall we say, a thing for explosive oil tanker trucks. Suddenly, morose Pine Cove turns libidinous and is hit by a mysterious crime wave, and a beleaguered constable has to fight off his own gonzo appetites to find out whats wrong and what, if anything, to do about it.
