The Doctor (Jon Pertwee) and his companion Jo Grant (Katy Manning) visit Stangmoor prison to see the Keller Machine, a device designed to suck the evil from criminals' brains. However, Doctor Keller is not all he seems… One of the most memorable and complex Who stories, The Mind of Evil (1971) has only been available in black and white since it was first broadcast. Now, thanks to insanely painstaking work by the Doctor Who restoration team, we can see it as it was orginally filmed. This special event in association with Shock and Gore not only includes the full serial but also a chance to hear from two of the restorers themselves, Peter Crocker and Steven Roberts, in conversation with Who archivist Paul Vanezis. This restoration was first screened at the BFI as part of their Doctor Who at 50 celebrations.
