When Officer Kate Sullivan (Gretchen Becker) storms a hostage situation, she is shot by the supposed victim who is apparently an accessory to the crime. She manages to return fire before slipping into unconsciousness, ultimately killing her shooter. The whole incident is captured on tape by an unscrupulous media crew who edit the footage to show Kate as killing a helpless victim. Now in a coma, Kate's only hope is another detective, McKinney (Robert Davi), who tries to clear her name. Unbeknownst to him, Matt Cordell (Robert Z'Dar), "Maniac Cop", takes it upon himself to clear Kate's name and exact revenge upon those responsible for smearing her name. His vigilante mission takes a twisted turn when he kidnaps Kate from the hospital and prepares for an unholy wedding in an abandoned church. When McKinney interrupts Cordell's deranged plan, an explosive confrontation may finally send the Maniac Cop to his final fiery doom.
