Two elderly gangsters are released from prison only to find they have trouble fitting in as old men who still take no guff from anyone.

In 1980, an assistant in the Department of Defense, Warren Lasky, is assigned by his mysterious chief Richard Tideman to visit the aircraft carrier USS Nimitz commanded by Capt. Matthew Yelland as an observer of the routines. Lasky learns that Commander Air Group (CAG) Richard T. Owens has a great knowledge of history. Out of the blue, the vessel faces a weird storm and they find they have traveled back in time to the eve of the attack of Pearl Harbor on 06 December 1941. When the two Japanese Zeros attack the motorboat of Senator Samuel Chapman, the crew of the Nimitz rescues the senator and his assistant Laurel Scott. But Lasky soon learns the senator had disappeared on that day and Capt. Matthew Yelland is planning to attack the Japanese. Will these actions create a time paradox?
