In Los Angeles, Dr. Henry Pride (Bernie Casey) is an accomplished and wealthy African American medical doctor working on a cure for cirrhosis of the liver along with his colleague, Dr. Billie Worth (Rosalind Cash). Desperate to create this remedy, Pride conducts unethical experiments on others and himself, which turns him into a white-skinned Frankensteinian monster with superhuman strength and invincibility. Pride begins a spree throughout Watts, killing prostitutes and pimps. After not being able to test his remedy on Linda (Marie O'Henry), he continues his rampage, which results in him being chased down by the police. Cornered at the Watts Towers, he attempts to escape by climbing up the towers, which leads to the police gunning him down and causing him to fall to his death.
