When American agents in Moscow try to recover a stolen letter implicating America in an anti-Red China plot, they discover a hornet's nest of treason, double agents, murder, and betrayal. The plot has as many switchbacks as a Formula One racetrack, and a pad and paper to keep track of the agents and their code names wouldn't hurt. Still, The Kremlin Letter is an interesting espionage movie with some good performances.~ Tana Hobart, All Movie Guide
