A dalek appears in Equestria - not just any dalek, but the one that had been corrupted by Rose Tyler's DNA. It has a choice of life as a pony, or dying, and finds that it cannot bear to die a second time. Thus begins a strange adventure as the dalek tries to find a place for itself in a world that is completely antithetical to its former existence and way of thinking...
...and why does that earth pony stallion look familiar...?
