Tora! Tora! Tora! Is the Japanese signal to attack - and this movie meticulously recreates the attack on Pearl Harbor and the events leading up to it. Opening scenes contrast the American and Japanese positions. Japanese imperialists decide to stage the attack. Top U.S. brass ignore its possibility. Intercepted Japanese messages warn of it - but never reach F.D.R.'s desk. Radar warnings are disregarded. Even the entrapment of a Japanese submarine in Pearl Harbor before the attack goes unreported. Ultimately the Day of Infamy arrives - in the most spectacular, gut-wrenching cavalcade of action.
