The Doctor, Amy and Rory find themselves in the American wild west sometime in the 19th century. The small town has a Marshal but they're not that keen on the new arrivals. They are also under threat from an alien, a half-man half-robot hunter who is out to eliminate the Doctor. Not the Doctor we know but another, Kahler Jex, who has escaped from his world. He's done many good things for the local community but his past is somewhat questionable. When the Marshall is killed, it's left to the Doctor to decide how best to proceed. Written by

Okay, so, our next trip... Oh! You know all the monkeys and dogs they sent into space in the 1950s and 1960s? You will never guess what really happened to them.
