Somewhere at sea, the crew of a fishing trawler visits a brothel-ship. The girls, under Captain Enceladus, their shady lord and master, welcome the sex-starved men. Max, the least experienced among the fishermen (both in fishing and in sex) is paired with Dayna, a young prostitute who appears to be having a crisis of conscience. While the other men are bewitched by the Siren-like girls, Max and Dayna have a different kind of connection. There is clearly something far more sinister going on aboard the mysterious vessel than sex at sea....
