Each episode presents a new true crime case, modern or historical. Michael Winner hosts, providing exposition through voiceovers due to low production values. He often delivers a patronizing moral conclusion.

One new true crime each week, either modern (the murder of Mrs X in the 1980s) or historical (Maybrick's murder in the 1880s). Michael Winner introduces the show and because of low production values, interrupts with 2 or 3 voiceovers to speed the plot. Winner usually manages to be as patronising as possible as he recounts the cloying moral-of-the-tale in his closing piece to camera.—Garryq
