Katherine "Kate" Woodville is perfect as a beautiful and devious spy in this excellent episode, shades of a JAMES BOND character if there ever was one.
Kate plays Felicia, a spy probably working for Russia, who has stolen only half of a top secret map that reveals NATO defenses. The M. I. team enters the picture, planning on doing a super switch and put a second fake map in her hands. Joseph Campanella is also very good as the notorious Captain Cherno, working in league with Felicia. Naturally, the rest of the mission is to turn them against each other, a familiar sub plot in many episodes.
There are some outstanding scenes here. Phelps is hypnotized so he cannot be tortured. Cherno, who is a work of art, holds a gun to his head and pulls the trigger --and you can see the bullet chamber and how many more "clicks" Phelps has left before he could be shot! Meanwhile, Rollin, who plays a spy, strikes an awkward relationship with Felicia (who can't be trusted) and the two are beginning to fall in love. This is evident by the close of the episode, without giving too much away. A very poignant scene, which is rare for the series.
A-plus acting on the part of Kate Woodville, who soon after this episode would guest star on STAR TREK in the role of Natira, which brought her much acclaim. Veteran actor Karl Swenson plays Colonel Dubov, best in authoritative roles.
A solid script turned in by Barney Slater, who was associated with LOST IN SPACE. About 10 years later he was killed by a hit and run driver, a tragic Hollywood ending.
