The Daleks
(aka The Dalek Invasion of Earth - Part Two)
The Doctor and Ian are taken prisoner by the Dalek and the Robomen. They are taken taken to the Daleks’ flying saucer. They are thrown in a cell with Craddock, another prisoner. Craddock tells them all about how the Daleks took over the Earth.
The Daleks identify the Doctor as having above average intelligence. They place a device in his cell. He uses it to escape from the cell but it was just a test. The Doctor does not get more than a few steps outside his cell before he is recaptured.
The rebels take care of Susan and Barbara. The rebels are planning an attack on the saucer where the Doctor and Ian are being held prisoner. Dortmun, their wheelchair bound leader, has made some bombs which he believes will be very effective against the Daleks.
Some of the humans disguise themselves as Robomen, an idea that Barbara thought up, and they use that scheme to allow them to get close to the saucer without being detected. They use the bombs and break into the saucer.
The Doctor is taken against his will to an operating room. He is sedated and operated on as the attack on the saucer begins.
