Hack(2002)

To some he's just a cabbie... but for people in trouble this ex-cop is a hero.

Hack is a crime drama following Mike Olshansky, a former Philadelphia police officer whose career implodes when corruption allegations destroy his reputation and cost him his family. Unable to move on, Olshansky reinvents himself as a cab driver, using his new position to patrol the city streets as an unofficial vigilante. Operating in the shadows of Philadelphia's underworld, he partners with sympathetic cops still on the force while pursuing his own brutal brand of justice. The series explores themes of redemption, corruption, and the blurred lines between law and vengeance as Olshansky navigates a dangerous path between his past and his fractured present.
