An ambitious enemy agent makes it a point of honour to break the resistance of one of them. He is a young, world-famous pianist, respected by his fellow prisoners. His capitulation may result in winning many others over to the enemy's side. An insidious game begins, full of sophisticated manipulation, threats and promises. Can the young artist, a loving father and husband, win a duel with an agent backed by the power and perfidy of the Russian system?
