Escape From Atlantis

During the first manned mission to Mars, three astronauts encounter a rogue comet. After they pass through the comet's tail, they are unknowingly transported ten thousand years back in time. Forced to scrub the mission because of irreparable damage to the ship and life-threatening injuries to the pilot, they crash land on the continent of Atlantis just weeks before it sinks. Will they too become a casualty, or will they be able to Escape From Atlantis?
