Unable to face her guilt over inheriting a morally questionable company when she turns 18, Ann runs away into the lawless wasteland of the New York City borough of the Bronx.

The Tigers’ leader, the Ogre, informs Trash that Chris was carrying a "gizmo" – a covert listening device that looks like a watch and works on the same radio frequency as the Manhattan police.

When he enters the Bronx, he kills two Riders, plants a golden ring in the gang’s headquarters, and then flees the scene.

During the party, a Manhattan Corporation private army, led by Hammer, invades the building and proceeds to massacre everyone there.

The idea for the film was first envisioned by producer Fabrizio De Angelis when he missed a subway stop for his Manhattan hotel and ended up in a dangerous neighbourhood in the Bronx.

De Angelis stated he imagined the idea of a futuristic city where young hoods would fight for their home.

[7] Variety praised Fred Williamson, stating that he "comes off as the best in the cast, handling himself smoothly in fight scenes which owe more to Italian sword 'n sandal programmers than recent violent epics.

[11] The review noted that these elements did not compensate for the films "sillier excesses" such as the roller-skating gang and that the leads of Stefania Girolami and Marco di Gregorio were bland protagonists.
