Dawn's world has fallen apart. Recovering from a suicide attempt, her psychiatrist sends her to a small seaside town to recuperate. While her sense of reality is blurred by strong medication and alcohol, she discovers a dying mutant mermaid on the beach. She nurses the baby mermaid back to health, and slowly becomes addicted to the hallucinogenic slime it secretes. As Dawn becomes friends with an attractive local man, the creature grows stronger, feeding off the sexual energy emanated by Dawn and her new lover.
