When the whalers hit Seaport after a good season Smith and Weir have their work cut out to keep trouble to a minimum.

""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.

When a gas meter is broken into in a big block of flats Weir and Smith think their hunt is only for a petty thief. What they encounter, though, is someone much more dangerous.

It's a busy night for Smith, Weir and Sergeant Watt when burglary is rife.
