Mick is one of the primary antagonists of the film, along with Ray Parkins (Audrie J. Neenan). Nothing is known about his history except that he was the psychotic leader of a gang of rapists who has no compunction about killing innocent people. Mick rapes Jennifer Spencer and her younger sister Elizabeth after Ray lured them under a bridge. Mick and Ray, along with fellow gang members George Wilburn, Kruger, Tyrone and Alby, all took turns brutally raping the two girls under the pier at the San Paulo town carnival.
Years later, Jennifer begins to exact her revenge on her rapists by coldly gunning them down. At the end of the film, Mick escapes the killings, then infiltrates Jennifer's plans and prepares to rape her once more (with help from Eddie and Carl) at the San Paulo carnival. They also ambush investigator Inspector Harry Callahan and he is eventually pushed into the San Paulo harbour, losing his .44 Magnum gun in the process.
However, Callahan rescues Jennifer by shooting his cronies along the boardwalk with his AutoMag (pistol), then kills Mick from the Giant Dipper roller coaster, falling into a moving carousel where the rapist is impaled by a unicorn's horn. When asked about Jennifer's handgun found on his body, Callahan says the gun belongs to the dead man, allowing Jennifer to remain free.
