It was the wrong day for a picnic! Mitch and Ryan head for the oil rig abandoned after a strange accident and spot a drifting yacht. Searching it they find a terrified young woman who says her host was pulled off the yacht by a weird sea monster. They have to abandon the yacht and use a rubber life raft to reach the oil rig where the gelatinous green stuff catches them.

Mitch is alarmed when a child he saved six years ago turns to Haitian voodoo now she is a teen-ager. He and Ryan investigate and need the help of a priestess, Madam Trudor, to save their lives.

Teague asks if they have ever heard of Knights Templar and then we see Ryan and Mitch confined in torture devices which are controlled with modern electronics by an Asian woman.

Mitch saves a young girl from drowning and then she tries it again saying she must die. He discovers she is possessed of a demon who then prefers Mitch.
