It's been six days since the attack on Pearl Harbor. Panic grips California, supposedly the next target of the Japanese forces. Everywhere in California, people are suffering from war nerves. Chaos erupts all over the state. An Army Air Corps Captain, a civilian with a deranged sense of Nationalism, civilian defenders, and a Motor Pool crew all end up on the trail of a lost Japanese sub that has picked Hollywood as their own target. Will these people be able to defend their homes? Will they be able to preserve the safety in California? Will they be able to get a hold of themselves?
