Time Bomb

A group of international scientists and archaeologists on a publicly funded dig discover a hidden city beneath the streets of Berlin. Constructed as a failsafe option for the Nazi party should they lose the war, the city is also home to Hitler's ultimate doomsday weapon- an Omega bomb designed to wipe out the human race- and it's just been activated. Now, crews of scientists must travel back in time to 24 hours before the disaster to stop the bomb from going off. However, they soon discover that, rather than going back in time for 24 hours as intended, they've been sent back 67 years to the height of Hitler's Germany.
