The game is set in a Hollywood version of 1930s Chicago, where one plays a private detective that has been hired to find out who murdered a nightclub singer named Johnny Rock.

The player must attempt to reach Johnny Rock's killer, shooting villains and interrogating individuals.

The game takes the player through the gangs of four gangsters with suggestive names - Measles, Mumps, Smallpox, and Lockjaw Lil, each of whom knew Rock and are suspects in his murder - and locations such as a warehouse, a pool hall, a garage and a casino.

Most other games produced by the company - with minor exceptions such as The Last Bounty Hunter, where the player can use a shotgun for a limited amount of time - feature no more than a simple pistol, which must be used to eliminate successive foes.

As in most rail shooters by American Laser Games, the DOS and 3DO versions include mouse and light gun support.

During the segment, Slattery stated that he hated video games, and later failed the challenge by shooting an innocent victim.
