In the first of a new series of Ultimate Emergency Bikers, biker cop PC Martin Smith gets more than he bargained for as he joins in the pursuit of a van driving at high speed. But the driver's determined to shake off Smithy and his colleagues who find themselves playing dodgems with stuff lobbed out of the back of the van.

Biker cop Lucy Watson gets more than she bargained for when she's called to an accident. A couple of lads have had a narrow escape from a lorry driver who reeks of booze.

There's been a pile up on the A13, one of the busiest roads in Essex and an elderly couple are trapped in their car. Biker cop Stomp's on his way, a hair-raising ride through queues of traffic as he races to the scene.

In the last of Ultimate Emergency Bikers, PC Martin Smith is on the trail of a driver who's far from safe at the wheel.It takes a while to bring him to a halt but it soon becomes clear why his driving isn't all it might be. He's way over the limit.
