After serving a false rap to establish his “wiseguy” credentials, undercover FBI agent Vinnie Terranova infiltrates the criminal underground of Atlantic City, where he could wind up dead with one slip of his cover.

In an attempt to take over Sonny Steelgrave's business, mob head Paul Patrice frames Sonny for several murder attempts he makes on the life of a special prosecutor.

A psychopathic murderer posing as Sonny's nephew double-crosses Sonny and holds Vinnie's girlfriend Gina hostage.

Vinnie jeopardizes his cover by going to the cops to get them moving on what he knows was murder.

When the cops put the heat on Sonny Steelgrave and bust up some of his secret deals, he smells a rat in the inner circle — and Vinnie finds himself suspect.

After his mother is mugged in Brooklyn, an enraged Vinnie sets out to find the punk who did it.
