One night in Detroit, during a shoot-out at a chop shop, Detroit cop Axel Foley sees his boss, Inspector Douglas Todd, getting killed by a well dressed man. Using his last breath, Inspector Todd tells Axel to get the man who shot him, and Axel says that he will do that. Axel does some looking around, and finds the killer's vehicle at Wonder World, a theme park in Beverly Hills, California. In Beverly Hills, Axel is reunited with his friend Billy Rosewood, who tells Axel that John Taggart is now retired and living in Arizona. Billy is now the deputy director of operations for joint systems interdepartmental operational command (JSIOC). Billy also has a new partner named Jon Flint. Axel checks out Wonder World, which is owned by Dave "Uncle Dave" Thornton. At Wonder World, Axel rescues two kids who are stuck on a ride that broke down, and after this, Axel is taken to see the park's head of security, Ellis DeWald, and Axel recognizes DeWald as Inspector Todd's killer. Jon refuses to believe this, because DeWald is one of Jon's friends. Ellis runs a counterfeiting ring that uses the theme park as a front. Axel is also falling in love with Janice Perkins, who works at the park. When Dave gets shot by DeWald's men, Axel is accused of being the man who shot Dave. With the help of Billy and Jon, Axel sets out to prove his innocence and get revenge on DeWald.
