An anthology series, each episode had a self-contained story usually in a thriller or horror style, and often with a twist ending.

Despite Australian television being in black and white in 1973, this series was produced entirely in color and on film to enhance its international appeal.

Each episode was introduced by Anthony Quayle, who appeared in a darkened studio surrounded by unearthly golden smoke imagery, frequently reminding viewers that "there is a touch of evil in all of us".

Australian actors in supporting roles included Jack Thompson, Elaine Lee, John Morris, June Thody, Tony Bonner, Neva Carr Glyn, Janet Kingsbury, Mirren Lee, Reg Evans, Peter Gwynne, Mark Lee, Carole Skinner, Briony Behets, Roger Ward, Rowena Wallace and Wendy Playfair.

The series was also screened in first-run syndication and later re-ran on TV Land in the US and ITV in the UK, with later airings in the 1990s on Bravo.
