Much against the wishes of Chief Ironside (Raymond Burr), Mark (Don Mitchell) goes undercover to smash an extortion ring preying on ghetto dwellers. It's a personal crusade for Mark: one of the ring's victims is his friend Gilbert, who is forced to pay huge sums of money each week lest harm befall his mother. This episode was cowritten by frequent Ironside guest star Felton Perry, who also appears as Gilbert. ~ Hal Erickson, Rovi
