A terrorist named Raimonde dies over the English Channel, rather than face arrest, due to the machinations of a... competitor, Mr. Zed. Zed is now positioned to weld a wide array of terrorists into a dangerous organization. To stop this, U.N.C.L.E. goes to Albert Sully, who knew Raimonde during World War II. But Sully has his own ideas about how to handle the case.
