Albion Firetrucks, a local company which makes fire engines, has the computer plans for its new high-tech prototype stolen, when Ken is knocked off his bike while couriering them to the managing director. He is rescued by Shandy Tremblett, a platinum-blonde Page 3 girl who is staying at the Coaching Inn while trying to "improve her education". When the prototype itself is stolen, Ken investigates. He uncovers a conspiracy between an American consortium, led by Ed Slatterley, and Albion's director, Sir Freddie Blackton MP. The intention is for Slatterley to buy Albion at a knockdown price (because the prototype and its plans are missing) and then, having asset-stripped the company, to close it down. Ken finds the prototype hidden in a barn. Ken, wearing a brass fireman's helmet, and Shandy, dressed in a Union Jack robe, stage a publicity stunt on top of the fire engine to raise public awareness and to persuade the government to allow a management buy-out to take place.
