Mission: Impossible - S5E16: The Missile (aka Torpedo)

What's the Story?

James Read, an enemy agent, is posing as an analyst to get to a top-secret U.S. missile guidance system being tested and steal the plans - the IMF must have him take back fake plans and unwittingly pass on the incorrect information to his superiors. Dana takes the place of Read's contact and he and fake boss Jim fake a romantic relationship so Read can get blackmail photos and use them to turn over the system. Read tells Dana of his plan to kill Jim, but before she can warn Jim, Dana is kidnapped by Hecker, a psychopath who believes Dana is a former girlfriend he killed. After Willy saves Barney from a firetrap meant for Jim, Paris and Barney manage to rescue Dana and alert Jim just in time to avoid a rigged car, convincing Read he's in the clear with the guidance system.
