Kojak: Mojo (1974)

Synopsis
In one of his occasional undercover assignments, Kojak (Telly Savalas) poses as a chemist. It's all part of a plan to flush out a gang of crooks who have stolen a valuable shipment of morphine in order to sell it back to the rightful owners for an exorbitant price. Naturally, Kojak pretends to be corruptible enough to attract the crooks' attention--a dangerous game which could cost him his life at any moment. ~ Hal Erickson, All Movie Guide
