Harry is searching for a group to provide entertainment at the Coaching Inn. He approaches Frankie Bass, a theatrical agent, who recommends a Country and West band, Bronco Billy's Boys. Harry hires them privately, bypassing Frankie's agency fee.

Ken falls for Bebe McLintock, their raunchy blonde singer, after he has to rescue the band when they break down on their way to the Coaching Inn. Frankie Bass turns up and demands her share of the takings. Bronco and Bebe are forever arguing and Bebe is angry that she is not given sufficient chance to sing her own songs. She runs away from the band - and ends up in Ken's bed! She is on the point of leaving the band and living with Ken. However Ken's luck does not last: before long Bebe (who turns out to be Billy's wife) goes back to the band after Billy decides her needs her to stay. He is prepared to give her top billing and to let her sing her own songs.

When White Lightning (Ken's beloved bike) is stolen, it is another member of the band, P

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.
