Steed, Gambit, and Purdey are inoculated so that they can attend the demonstration of S.95, a new gas that can send people to sleep instantaneously. But when a quantity of the gas is subsequently stolen by the criminal Brady, he uses it to render the whole of London unconscious. Awakening on a particularly quiet Sunday, Purdey, Steed and Gambit search for one another, and encounter Brady’s men, who have set about looting the city. Eventually Steed and Gambit meet up, and from the top of the Post Office Tower spot the looters' departure point; they hijack their escape helicopter - which just so happens to be piloted by Purdey. But the three of them are so exhausted, that they fall fast asleep at their heroes' welcome.
