This powerful drama of patriotism, betrayal and suspense combines gorgeous decors and thousands of extras. In 1776 Poland, nobleman Boleslas Vorowski heads a secret liberation movement against Russia and learns his childhood sweetheart, Sophie, loves his friend, a Russian officer. When Vorowsky is wounded in battle, his mentor, the inventor Baron Wolfgang von Kempelen, constructs a marvelous chess-playing automaton which, when summoned by Catherine the Great, holds the fate of Polish independence by a single, suspenseful chess game.
