Clockwork is your average stallion, hard working, dependable, maybe a bit obsessive about the placement of his tools of trade. One day after a long afternoon of attempting to fix a clock he receives an uninvited visitor in the form of a confused (and confusing) grey pegasus known only as the Doctor. Now he and the Doctor, still adjusting to a completely new body, must find the Doctor’s missing friend and try to adapt to each other as best they can. Little do either of them know that a dark shadow watches from behind it all and will do everything it can to make this the Doctor's final adventure.
