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, All Movie Guide
