Description: After a lengthy absence, the Doctor returns to Earth and scoops up Amy and Rory for yet another adventure. He also manages somehow to include Rory's dad, Brian Williams. Those aren't the only travelers however as Queen Nefertiti and big-game hunter John Riddell are also on board. The TARDIS next reappears on board a large ship and the Doctor is delighted to find a cargo of prehistoric dinosaurs on board. Using the ship's computers, Amy determines that the ship's crew is nowhere to be found.
