S3·E14 The Snow Game

Hooker, Romano, Stacy and Corrigan are involved in an undercover operation to nail a large cocaine dealing ring, when a highly respected fellow officer is killed, execution-style, by the ring, who are on to him. Tracking down one of the thugs involved, Romano is badly injured by a gun-shot wound, before Hooker captures the goon, who gives the lead of a crooked bail-bondsman who is involved with the dealing. Against the wishes of a DEA, Hooker and Corrigan go undercover as drug dealers, with Stacy posing as one of their carriers, to infiltrate the dangerous ring via the bail-bondsman and catch them in the act.
