Beach decides to set up a drugs exchange with two men believed to be connected with Smiler McCarthy.

Beach decides to set up a drugs exchange with two men believed to be connected with Smiler McCarthy. Despite protests from Bones, Beach assigns Mark Kemp (the commissioners' nephew) to be the bait and hand over the money. Roy Leyton grudgingly gives Beach the £2000 needed for the exchange despite the fact that funds are low.

Mark waits with the money whilst being watched by Bones and Strings who are stationed in the flat of an old lady who rather likes Strings guitar playing (though Bones finds it a pain). Ash meanwhile is lying behind a wall and de Sade and his gang are squashed in a saloon car with the film crew.

The two guys arrive and Mark gives them the money despite the fact that Bones told him to ask to see the merchandise before paying up. They now have no drugs and have lost £2000. Bones is furious and demands that he meet the men on the second attempt. Beach agrees but insists that Mark accompany.

Bones demands another two grand off Leyton who agrees to meet him with the money at the rendezvous. Again the Good Guys station themselves around the area: Ash in the boot of the saloon car, de Sade and his gang plus the film crew squeezed into a mini. The time is ticking by and Leyton has not arrived with the dough.

At the station Leyton reveals to Beach he's lost it. The men arrive and Bones tries to keep them talking but they are interrupted when they hear Ash having a panic attack in the boot of the car. Beach decides to try once more this time he obtains the two grand from his mother's bank account. Again they fail when de Sade sets off a tear gas bomb in the mini and the men who have come for the cash realise they've been set up. They run for it taking Mrs Beach's two grand. DI Beach has a lot of explaining to do.
