It is the post-apocalypse on a planet called New Terra (even though a rather intact Manhattan is clearly visible in some of the outside shots and Central Park in others). People in rags fight and die until the evil rule of Dark One and his robot army, led by the incredibly campy and over the top Valaria (Angelica Jager).
Neo (Norris Culf) arrives at this hell on ..er.. New Terra and is persuaded to help Deeja (Nadine Hartstein) rescue her scientist father Klyton (J. Buzz von Ornsteiner) from the Dark One as he has invented a weapon to finally defeat the Dark One. Neo assembles a mixed crew of scantily clad heroes and an annoying robot to face a series of dangers and quite a few rather inept fights.
The plot alone means this film won't be a cinematic classic but films like New Barbarians had ropey plots too but were still great fun to watch. The main problem with Robot Holocaust is that it is all so lifeless and dreary. Fights are slow and pointless, the characters move between somewhat similar looking though apparently completely different areas of the "wasteland" slowly for no reason. It is a terrible film, one of the worst ever. It is however, well worth watching for Angelica Jager alone. An astonishing performance is more ways than one.
