Short summary
Capturing the Doctor and Leela, the citadel guards are quite pleased to have more subjects for their public executions, but it only fires up a Trog revolt instead.
This episode was watched by 8.9 million viewers on its original transmission.
All four episodes of the serial ran short of their allotted running time, forcing the use of extended and repeated shots for padding. This episode in particular was so much in need of padding that the reprise was much longer than usual.
