All humans have been killed except a handful who are being pursued by none other than the Robot Monster. The setting looks like Arizona. RM is able to communicate with the humans (which he refers to as "Hu-mans") through a device that looks like a dresser with a mirror and bubbles coming out of it. RM doesn't have a vehicle so he has to walk everywhere. His outfit is particularly great -- a cross between a deep sea diver's suit and a gorilla costume. The tension is, well, interesting, as the hu-mans strive to outsmart RM. Wow!
