The Protectors is a British television series, an action thriller created by Gerry Anderson. It was Anderson's second TV series using live actors as opposed to electronic marionettes, and also his second to be firmly set in contemporary times. It was also the only Gerry Anderson produced television series that was not of the fantasy or science fiction genres. It was produced by Lew Grade's ITC Entertainment production company. Despite not featuring marionettes or any real science fiction elements, The Protectors became one of Anderson's most popular productions, easily winning a renewal for a second season. A third season was in the planning stages when the show's major sponsor pulled out, forcing its cancellation. The Protectors first aired in 1972 and 1973, and ran to 52 episodes over two series, each 25 minutes long - making it one of the last series of this type to be produced in a half-hour format. It starred Robert Vaughn as Harry Rule, Nyree Dawn Porter as the Contessa Caroline di Contini, and Tony Anholt as Paul Buchet. Episodes often featured prominent guest actors.

The Main Chance was a British television series which first aired on ITV between 1969,1970,1972 and 1975. A drama, it depicts the sudden transformation in the life of solicitor David Main who relocates from London to Leeds.

The TARDIS materialises not far from Paris in 1794 — one of the bloodiest years following the French Revolution of 1789. The travellers become involved with an escape chain rescuing prisoners from the guillotine and get caught up in the machinations of an English undercover spy, James Stirling — alias Lemaitre, governor of the Conciergerie prison.
