A group that fundraises to buy medicines for treatment of third-world countries has lost a $1 million shipment to thieves.

When Sam enlists Michael's help to recover the drugs, Mike learns to his dismay that the gobetween is Virgil Watkins, a previous client in last season's episode "Unpaid Debts." Mike is all for helping the charity, but warns Virgil not to hook up with Mike's mother Madeline as it nearly got her killed last time they were together.

Sam, Virgil and Michael cook up a plot to force the drug thief, a man named Gerard, to reveal where he's hidden the stolen cache. With the plan, Sam sets himself up as the buyer and arranges to get Michael on the inside (his cover - a timid chemist protecting his "own" stash of illegal medication.

The plan falls together easily and professionally, the money is finally returned to the charity and all is restored to save the world's children.

Meanwhile, the trail of weak Burn information continues as Michael tracks information on the Dragonov rifle that was uncovered in the last episode through a contact of Fiona's.
