A disturbed guy witnesses a work colleague on fire but does nothing to help, despite the protests of his fellow workers. It later turns out that he was abused by his mother as a child by having his arms burnt over the naked flame on the cooker as punishment for his sins, and so therefore he decides to take it out on random women by luring them back to his house to torture and burn them as well.

One scene in particular is quite chilling; he entices a florist back to his house, and after knocking her unconscious, she wakes up naked and chained up in the basement and set alight from his flamethrower after being doused in gasoline. This sequence is one the reasons the film remains banned in the UK, after it fell foul of the notorious Video Nasties list back in the 80s.
