The French Connection II (1975)

Synopsis
This sequel to the Oscar-winning The French Connection picks up almost exactly where the earlier film leaves off. Still on the trail of drug kingpin Frog One (Fernando Rey), narcotics officer "Popeye" Doyle (Gene Hackman) leaves his Manhattan stomping grounds and heads for Marseilles. There, Popeye is captured by Frog One's minions, who pump him full of drugs in hopes of turning the cop into a hopeless junkie. After a grueling "cold turkey" treatment, Popeye is up and about and chasing after the villains, determined to mete out justice. ~ Hal Erickson, All Movie Guide
