In the Summer of 1971 Canadian station CBC transmitted selected episodes of Doomwatch Season 1 and 2 as one season. There is some confusion as to whether they actually transmitted The Logicians, so if you can help us out here, let us know!

The CBC is responsible for retaining the only known copies of many episodes of Doomwatch, almost the entirety of Season 2 from episodes 1 to 12. Interestingly, Season 2, Episode 13 - Public Enemy was never shown but is the only one from Season 2 retained by the BBC in it's original 625 Line PAL format.

In the following run of episodes below the CBC did not actually show but retained what is now the only existing copies (as NTSC 525 Line) of:

Season 1 - Episode 10 - Train and De-Train  (NTSC)
Season 2 - Episode 1 - You Killed Toby Wren (NTSC)

CBC, also kept the only copy of the transmitted version of
Season 1 - Episode 4 - Tomorrow, The Rat

The following is a synopsis for Doomwatch that Canadian TV station CBC used for their original transmissions. Thanks to their archive for the following information.

 A description of Season 2 follows...





'Doomwatch', one of the most popular television drama series of recent years, returns for a new thirteen-week series on Monday December 14.

When the first series was shown the terms 'technological hazard' and 'environmental pollution' were little known. It can be justly claimed that 'Doomwatch' not only gave a word to the language but also helped draw attention to the great ecological hazards that threaten the human race.

The programme will continue to do this through its prime function which is to entertain. Quist and his team are the contemporary counterparts of St. George. Quist's dragon spouts more than fire and brimstone but the conflict is the same.

The first story is 'You Killed Toby Wren' by Terence Dudley. When Wren is killed while dismantling the 'Byfield' bomb, Quist is held responsible in that he failed to obey orders and obstructed the police. The Minister sees this as a chance of removing the thorn in his side and orders a Tribunal of Inquiry. Ridge, who also blames Quist for Wren's death, pursues a line on human/animal hybrids and is profoundly shocked by what he discovers. Will he speak for or against Quist at the crucual enquiry?

As in the first series, John Paul plays Quist, Simon Oates plays Ridge and Joby Blanshard plays Colin Bradley. Two new characters are introduced - John Nolan as Geoff Hardcastle and Vivien Sherrard as Barbara Mason - and the guest stars are John Barron, Donald Morley, Edward Underdown and Macdonald Hobley.

Devised by Kit Pedler and Gerry Davis. Produced and directed by Terence Dudley.

DOOMWATCH (c) Metronet

The code name "Doomwatch" is the term applied to a small, highly educated group of British scientists dedicated to uncovering and destroying the many extreme dangers posed to man by modern science and technology. Polluted oceans and air, chemically perverted foodstuffs, the onerous after-effects of scientific research, the ever-increasing loss of privacy –all are symptoms of our modern society and all come under the scope of the zealous band of "Doomwatchers" who will stop at nothing to prevent the balance of nature from being forever poisoned. Headed by Dr. Spencer Quist, the Doomwatch team encounters almost as much opposition from the various government departments involved with ecology, as those forces which knowingly break the law. But the dedicated team will use any means, however unconventional and including violence, to carry out their mission. It's a fast-paced chilling adventure series from the BBC, that deals with the real villians of our modern world–the forces of ecological disruption that could eventually destroy the planet it–self. Featuring John Paul as Dr. Spencer Quist, Simon Oates as Dr. John Ridge, Barbara Mason is played by Vivien Sherrard, John Nolan is Geoff Hardcastle and Joby Blanshard is seen as Dr. Colin Bradley.

Friday July 2nd 1971 was the series debut of Doomwatch that ignored episodes 1 to 3 of Season 1 and went straight into Episode 4...

Tomorrow, the Rat

A scientific experiment using rats to improve the genetic qualities of man backfires causing a horde of vicious, highly intelligent and fertile rats with a taste for human flesh to be let loose on London. All of Doomwatch's energies are brought into play to defeat these cunning monsters created in the laboratory.

 It's amusing to note that the following show FBI is entitled Death Watch.

There is a scathing review of a Doomwatch episode from Canada's Globe & Mail on July 5th 1971 referring to the broadcast of Tomorrow, the Rat on 2nd July 1971. It is interesting to note that the episode is referred to as The Day of the Rat.


Tries for adventure, Doomwatch just dull

By Kaspars Dzeguze

"Doomwatch must have struck some television executive as a portentous title for a vaguely scientific, allegedly adventurous series of hour-long shows which have their roots in that media-nurtured garden of weeds—ecology.
But to judge by Friday night's premiere offering, The Day of the Rat, there's little chance Doomwatch will tick off the minutes to ecological disaster, since this is clearly another in the series of wildly inaccurate forecasts of things to come.
It's hard to understand why a story revolving around the breeding and escape of intelligent, carnivorous rats (rattus sapiens, as one of the Doomwatch scientists whispers in a technical aside), with a preference for human flesh, who end up terrorizing London, should be so lethargic and un-inspired.
The show's staff could surely have cribbed enough ideas from the monster-creature films that abound to produce an hour crammed with effective second-hand ideas. But no—it seems pride demanded an original disaster unblemished by previous failures. And how original is the ecology angle now? Perhaps Doomwatch will demonstrate uniqueness in the subsequent weeks through the very depth of its fall."

The Globe and Mail, a Canadian Newspaper dated June 26th 1971 has this to say about the screening of Series 2 of DOOMWATCH on CBC...

"Doomwatch—The first fictional series, as far as I know, to commercialize the current pollution awareness. It's a BBC series about a group of scientists assigned to protect the environment by hook or by crook. Starting July 2nd at 10 p.m."
