An undercover agent is sent to infiltrate bootleggers in the Florida Everglades, but winds up lost in the swamps and stuck in a decrepit hotel with a few of peculiar inhabitants. What starts off like a police actioner quickly morphs into an unholy fairy tale of Southern Gothic melodrama and horror.

Following a limited release, this mid-60s Southern Gothic melodrama disappeared into thin air but has since grown in cult status. A terrifying B-movie nightmare about deranged bootleggers, the film is suffused with a sinister mood, outré performances, and chilling, black-and-white imagery.
