Dramatisation of the true story of the notorious "acid bath murderer" John Haigh, who murdered women and disposed of their bodies in vats of acid in the 1940's. He was only caught when the gallstones of one of his victims, Mrs Durand-Deacon, failed to dissolve in the acid and were detected by the pathologist who examined the residue from the acid bath.

Haigh meets the Hendersons at the seaside and comments "splendid weather for February!" (it was in fact 12 February 1948 when he killed them). He is then seen driving Archibald Henderson to his workshop down a road with trees in full leaf; this must have been filmed in May or early June. See more
