Ssssssss | 1972
College student David Blake gets a job as lab assistant to Dr. Stoner after the doctor's previous assistant mysteriously leaves town. Dr. Stoner is doing research with venomous snakes and begins David on a course of injections to protect him against being bitten. Before long, David notices some strange side effects from the shots. By now, he and Stoner's daughter Kristina are involved, and the doctor disapproves of their relationship. When Kristina visits a carnival freak show, she is alarmed that its "snakeman" looks very much like her father's precious assistant. Then, David realizes that he is being transformed into a King Cobra.
