But Hedy is also intelligent. At lavish Vienna dinner parties, she overhears the Third Reich's plans. One night in 1937, desperate to escape her controlling husband and the rise of the Nazis, she disguises herself and flees her husband's castle. She lands in Hollywood, where she becomes Hedy Lamarr, screen star. But Hedy is keeping a secret even more shocking than her Jewish heritage: she is a scientist. She has an idea that might help the country and that might ease her guilt for escaping alone -- if anyone will listen to her. Based on the incredible true story of the glamour icon and scientist whose groundbreaking invention revolutionized modern communication.
