The Bill - Diane Noble chases a limo onto a building site

Wednesday 5 December 2007 8:00pm - 9:00pm on ITV1.

PCs Diane Noble (Kaye Wragg) and Will Fletcher (Gary Lucy) respond to a call about a stolen limousine and chase it onto a busy building site. The car jackers manage to run away, leaving the officers to deal with a scantily clad and scared hen party trapped inside the car.

Sergeant Stone (Sam Callis) finds a bag of cocaine in the boot and discovers the original driver, Dave Latham (Sam Hazeldine), was dragged out of the car and beaten up. Inspector Gina Gold (Roberta Taylor) goes to Dave's house, where she finds his pregnant wife, Danielle (Katy Helps), bloodied and unconscious.

Elsewhere, DS Stuart Turner (Doug Rao) meets up with his driver Trevor Jones (Sid Owen), who tells Stuart he saw Dave that morning and explains there are rumours about someone using limousines to get cocaine to customers.

At St Hugh's, Danielle identifies her attacker as Lloyd Carter (Jody Halse) who is brought in for questioning. Cagey at first, Lloyd finally confesses that he was paid to beat Danielle up by Piers Halston (Dominic Power), Dave's boss.

Meanwhile, Trevor takes it upon himself to organise a meeting between Stuart and Dave. Dave confesses he has been 'watering down' the cocaine in order to make some money. When Piers found out, he sent Lloyd after himself and his wife.

After explaining that Piers deals drugs through a car valeting firm, DC Mickey Webb (Chris Simmons) is sent in undercover as a city banker to order a limo with drugs included. With the other officers waiting for to storm the valeting business, Mickey becomes anxious as he realises Piers is on to him.
