An Englishman named Wilson travels to Los Angeles to investigate the death of his daughter, Jenny. She reportedly had died in a car accident, but Wilson suspects she was murdered. Recently released from a British prison, he is a hardened man. Arriving in Los Angeles, he meets Jenny's friends Eduardo and Elaine and questions them. Finding they pass his initial inquiry, he elicits their help in investigating Jenny's death. One suspect who emerges is Jenny's boyfriend, a record producer named Terry Valentine. Investigating him it's learned that besides his legitimate record company business, Valentine has involvement in drug trafficking. His involvement is managed through his security consultant, Avery. Wilson locates a warehouse used by the drug trafficker and questions the men there. Laughing at him, they beat him, insult his daughter and throw him out onto the street. Undeterred, Wilson draws a hidden pistol and returns to the warehouse, shooting dead all but one of the employees. As the survivor flees, Wilson shouts "Tell him... I'm coming!"
