Un espion de trop

Charles Bronson stars as ace KGB agent Col. Grigori Borzov in Don Siegel's adaptation of Walter Wager's Cold War thriller. It seems that in the 1950s, at the height of the cold war, the Soviet Union planted a network of agents in the United States. They were programmed, under hypnosis, to blow up key military installations when activated by hearing a line from a Robert Frost poem. In the 1970s, Nicolai Dalchimsky (Donald Pleasence), a fanatical KGB agent, has decided to begin activating this network. The Kremlin, which had no awareness of the program, finally grasps what has happened after a series of explosions occurs at abandoned U.S. installations. Realizing that they can't reveal the problem to U.S. officials, they choose to send their best agent, Borzov, to stop Dalchimsky before he starts WWIII. Along the way Bronson is forced to work with another KGB intelligence officer, Barbara (Lee Remick), who proves to be a double agent, as well as accepting help from computer expert Dorothy Putterman (Tyne Daly).
