Officers Strunk and Mattingly patrol the "duplicipality" of South Lyons and Underglen Township. During a follow-up call to "über citizen" Mr. Pedanski, 76, they're informed of an illegal casino operating nearby. They don't let on, but they already know: It's run by fellow cops. When Strunk and Mattingly's attempt to join the scheme is rebuffed, Mattingly visits the casino, off-duty. He plays "Kentucky Three Finger" and breaks the bank. Soon, he and Strunk receive threats. Their cruiser is bugged. Neighborhood vigilantes raid a gambling den. Then the higher-ups in the department seek to split up Strunk and Mattingly. When the schmlanx hits the oscillating rotary blade, retaliation erupts in the form of arson, "porn bombs" and worse: Pedanski is viciously attacked and the son of Mattingly's girlfriend is kidnapped. Strunk and Mattingly finally realize it's the police department that should be wrapped in crime scene tape. Will their new-found sense of justice win the day ... or get them killed?
