Miss Winters has given Sarah a huge scare, activating the K1 Robot, which refused to attack her, because of its prime directive. The Robot explains its purpose, to aid humanity. Sarah relays her story to The Doctor and UNIT, they act by talking to Professor Kettlewell and send Harry undercover at The Think Tank. Miss Winters and Mr Jellicoe task the Robot with its next mission, to kill a Government minister, distressed after its conflict with its Prime Directive the Robot returns to Kettlewell. Sarah attends an SRS meeting, a group of individuals with ideas of how the world should be run. A trap is laid for the Doctor, where he encounters The Robot.
Miss Winters continues to be a nasty piece of work, that severe haircut and sharp voice. She's more then a match for our Sarah Jane, I like how she very calmly tries to turn the Robot against Sarah.
It seems so odd watching Tom driving Bessie, definitely Pertwee only!
It's a very well acted episode, I have to say in particular I find it a really strong performance from Lis Slden, she's got a definite sparkle in the eye. They gave Sarah a character that could act on her own initiative, it was refreshing for the companion to act independently. It's good fun 8/10
