Told to "Get lost", a robot does so by mingling in with a group of 20 other identical robots. Unfortunately, as this particular robot has had its 'First Law' modified to allow it to permit a human to come to harm, and so must be found. Like a number of Asimov's 'robot' stories, this tale involves solving a problem generated by a robot behaving in a way that is ostensibly contrary to the author's iconic 'Three Laws of Robotics' but lacks the cleverness of the original short story (notably, there is no explanation of the rogue robot's final actions and the real problem of having robots that can allow a human to come to harm is never addressed (especially considering the space-station's logic behind bypassing this part of Law 1 is sound)). Maxine Audley is good as robot guru Dr. Susan Calvin but the rest of the characters are simply ciphers (Gerald Flood is particularly weak as robot hating Black). The robots themselves are awkward and cheap-looking, and some level of suspension of disbelief is required to imagine them moving fast enough to pass/fail the elaborate tests set up to identify the modified tinman. Worth watching as the only surviving episode of the early British sci-fi anthology and for the few minutes you get to spend with the great Boris Karloff.
