Pinhead is set loose on the sinful streets of New York City to create chaos with a fresh cadre of Cenobitic kin.

In Las Vegas for a quicky divorce, a just-paroled ex-cop and his wife wander into the Top of the World Casino, run by the shady Charles Atlas. They win big, right as the casino is being robbed. The police believe their big win was a staged diversion, and the two of them become suspects. Over the course of the evening and next morning, the two attempt to escape to surrounded casino, and to prove their innocence, as well as to save their marriage.
