The film traces the life and deeds of a true life serial killer, John George Haig AKA the Acid Bath Murderer. Whilst in jail for fraud in the thirties he accidentally discovers the effect that acid has on animal bodies. He subsequently "offs" a series of people including a couple a family and three strangers by inviting them to his "workshop". He dissolves the bodies in oil drums full of acid. The film cuts to flashbacks of his upbringing by zealously religious parents, but steers clear of obviously blaming the parents for the son's murderous behaviour.
The film has a similar attention to detail as "10 Rillington Place" and Martin Clunes is excellently creepy as the charming Mr Haig. The contrast is small between Haig's day-to-day behaviour and the actual murders and disposals of the body but fascinating, leading to comparisons with Richard Attenborough's portrayal of Christie in 10 Rillington Place, but this film is more darkly humorous.
The film is written by Taggart creator Glenn Chandler and directed by Harry Bradbeer who directed most of the excellent BBC series "The Cops".
