""It's going to be one of those nights"", pronounced Sgt. Percy Twentyman, and he wasn't far wrong. Steele and Lynch have to cope with the aftermath of a traffic accident in which a drunken driver has killed a motor cyclist and his pillion passenger. Small time felon Grandpa Maddigan blows up the safe in the Gas Company office, Watt and DCS Robins are hot on the trail of the notorious Comber gang, and Twentyman himself gets more than he bargained for when he tries to break up a free-for-all in the Tabernacle pub.

Alby Rafferty, an over-zealous car enthusiast, is not past redemption according to John Watt. But Watt is not the only influence in Alby's life. So when Mr. Cull's shiny new white car is driven off from under his nose, it is not for use in a robbery - just Alby indulging his passion.
