Prehistoric WWII

It's May 1945. A mysterious storm pitches a US Destroyer and a German U-boat engaged in battle millions of years back in time. Prehistoric creatures swarm beneath the sea and terrorize the land. With dinosaurs and other deadly behemoths threatening their crippled vessels, Captain TW Brazo of the USS Sutton, and Commander Christoph Neuzetser of U-616, are forced to redirect the fight toward a common enemy. Dinosaurs' crushing jaws and blade-like teeth meet frail human flesh protected only by the limited supply of ammo fired by automatic weapons. It's a race against time as survivors' search for a way back home. As brutal as the Second World War had become, nothing prepared the crewmen for the ever-threatening dangers in this action-thriller!
