Undercover Las Vegas police officer Vincent Downs, who has a lot of enemies, is caught in a high stakes web of corrupt cops and the mob-controlled casino underground. When a heist goes wrong, a crew of homicidal gangsters kidnap Downs’ teenage son T. In one sleepless night, Downs will have to rescue his son, evade an internal affairs investigation, and bring the kidnappers to justice.

Mulvaney and Naphtlene are partners. He managed to escape from Hell (Mulvaney), and she's straight from Heaven (Naphtlene). Together they are an entertaining pair of "Midnight Meat Mop Detectives," or in terms that are easier to understand...demon hunters.
