S3·E11 Undercover Affair

Hooker, Romano, Stacy and Corrigan are staking out a small-time drug dealer when they find that a major drug supplier is involved – who is being staked out in a Federal investigation. Hooker is ordered to keep well away from anything to do with the Fed operation and any of the smaller dealers which may be involved with the drug ring, something which proves to be difficult and results in Hooker being suspended. But an old flame, who is a Fed agent, is undercover posing as the girlfriend of head of the ring, and Hooker, fearing for her safety, is determined to put the ring out of operation himself - even if it costs him his job.
