Overview: Victor Ragar, a cellist at a music conservatory that fronts for an Eastern Bloc freedom movement of which he is the leader, is in danger of being assassinated by a compatriot who accuses him of betraying the cause. The would-be assassin, Paul Delorio, also has a personal motive- Victor ran off with Paul's wife while Paul was in prison in the old country. The conservatory's director, also a member of the movement, hires Checkmate to protect Victor.
