Director Anthony Mann's final film (Mann died during the filming, and the production was completed by the film's star, Laurence Harvey) is a kitchen-sink espionage drama with Harvey as Eberlin, a Russian spy and double-agent, homesick and pining for the Russian steppes. It is in this risky mood that Eberlin falls in love with the emaciated Caroline (Mia Farrow). Complications arise when he is directed to kill a Russian spy -- but the Russian spy happens to be himself. ~ Paul Brenner, Rovi
