Sam Hibbing, a major Syndicate drug dealer, stole three tons of amphetamines from a chemical plant and hit the stash in a secret location - the IMF must get it before he sells it. The IMF replaces Hibbert's drug-addicted daughter Margaret with Casey and her new friend Jim, who turns out to own a charter plane and served time for murder. Meanwhile Barney teams up with Hibbing's buyer Dayton to purchase the drugs but they must have them the next day - Jim sets it up so Hibbing's regular courier gave drugs to Margaret/Casey, leaving Hibbing with no other choice then to use Jim as the delivery man. Hibbing sees through Casey's disguise and she escapes, but Hibbing tries to stop Jim - Barney and Willy stop him and Margaret goes into rehab.
