Episode Overview
Selby, a double agent working for the U.S. within an enemy intelligence agency, finds himself under suspicion from his boss, Kellerman. The IMF steps in to protect Selby and eliminate Kellerman. Frustrated, Selby voices his concerns when Kellerman takes Marceau, a courier aware of Selby's true identity. He insists that Kellerman is the real traitor. Disguised as a government official, Rollin gives Kellerman 24 hours to extract information from Marceau. Meanwhile, Kellerman, believing Agent Jim has kidnapped Brocke's girlfriend, teams up with Brocke to corner Selby. A staged video leads Brocke to turn against Kellerman, but his girlfriend later retracts her claim. As Marceau is rigged with explosives, the IMF intervenes with knockout gas and uses liquid nitrogen to rescue him just in time.
