David Redding is a photographer and a spy working for the other side, who has supervised the infiltration of 150 agents into the U.S. The agents are apparently carrying some kind of biological plague, and only Redding knows the code. The IMF must get it from him. To do so, they set up Cinnamon as a former fashion model and scientist married to Jim who is working with a bacillus-suspension formula. This gives Redding a reason to accept the assignment - he tortures ""Jim"" who claims the U.S. is planning a nuclear strike. Redding and his assistant Morley plan to take refuge in Redding's bomb shelter and command center after sending a signal to his country (which is blocked by Barney), but Rollin and Willy arrest them. When the IMF fakes a nuclear attack Redding leads the others to the shelter, then ""kills"" Willy. He tries to send more coded messages (again, blocked by Barney), and Rollin witnesses Redding coding them. At the end he leaves as it is revealed that the IMF switched Redding and

Selby, a double-agent for the U.S. within an enemy country's intelligence service, is suspected by his superior, Kellerman. The IMF must keep Selby in the clear and eliminate Kellerman. Selby complains when Marceau, a courier who knows about Selby's identity, is taken from him by Kellerman. Selby claims Kellerman is the double-agent. Rollin, as a government official, gives Kellerman 24 hours to break Marceau. Using his underling Brocke, Kellerman works with Rollin to trap Selby. Kellerman comes to believe that Agent Jim has kidnapped Brocke's girlfriend to force Brocke to give away Marceau's location to Selby. In reality, Stephanie is shown a fake split-screen of Jim conspiring with ""Kellerman"" (Rollin in disguise on tape!) to kill Brocke and eliminate Marceau. Brocke believes Stephanie and accuses Kellerman but she recants under pressure. Meanwhile, Marceau is wired to an explosive. When Stephanie recants the IMF break in using knockout gas and use liquid nitrogen to free Marceau. The

Jim Phelps poses as an amnesia victim in order to retrieve a stolen isotope, one that could make nuclear weapons affordable to any country.

The team must steal a rocket laser and smuggle out Father Bernard and his list of Western operatives. Bernard puts the IMF in contact with Wittstock, who gets them the laser. Wittstock is killed after delivering the weapon and Police Colonel Eckert seals up the country to capture the IMF. Bernard dies of a stroke but gets the list, but nightclub owner Eric Schilling saw Dana with Wittstock and tries to take advantage of the situation to profit. When Barney splits the laser into five parts for the team to smuggle out of the country, Schilling gets hold of Dana's part and the team has to get the part from Schilling while escaping through the heavily-guarded airport. Paris in disguise buys the part from Schilling, leaving him to be captured by Eckert while Paris drops the disguise to escape, leaving the part to be recovered by the rest of the team. Then the IMF secretly blend in with an arriving broadcast crew from England just as the crew are told their visas have been revoked - the IMF

Reese Dolan is the new Syndicate heroin distributor on the East Coast. Dolan uses an island base off the coast of northwest Africa and is going to use it as a distribution point for heroin into the U.S - the IMF must identify his overseas opium source and get the evidence to convict him. Dolan is being financed by an underworld figure, Madame Renada, whom he has never met, so Jim and Barney fly him and his men not to the island but to a lookalike off the coast of Georgia, where Casey assumes the role of Renada. Reese calls his distributor in Istanbul and the IMF has the delivery plane taken into custody. An IMF flyer makes the delivery which Dolan apparently converts to heroin and sends on its way, while Reese's supplier, Hajii, suspects a double-cross when his pilot doesn't return and calls Dolan's distributor, Cleff. Willy tries to sell heroin to Clegg and then is ""forced"" to tell that Dolan still has it, then lead Clegg to the fake island. Dolan finds out he still has the opium, and
