The Motorway Cops come face-to-face with their worst nightmare as they are called to detain two women who are caught walking on the M6 motorway. As the PCs arrive the women make a run for it, into the path of a 44 tonne lorry. The accident forces a total closure of the M6 leaving motorists stranded in a 15 mile traffic jam and the cops locked in a life or death battle to save the injured women.

PCs Griffiths and Toal are involved in a high-speed chase which takes them into Birmingham city centre, and PC Richard Elliot is called to a lorry park off the M6 where a gang has been disturbed while attempting to steal the load from the back of a lorry. Also, more than 20 motorway cops, a dog team and the West Midlands Police helicopter are involved in an operation to stop a gang involved in a cash-in-transit robbery.

At night, a lorry jack-knifes on an unlit section of the M6, and two cars have ploughed full-speed into the underside of its trailer. The roofs of both cars have been taken off in the impact, and one man is dead. But, miraculously, three others have survived. It's up to PCs Elliot, Bullard and Shail to find out if this was simply the hand of fate or if someone is to blame.

The Motorway Cops are after runaway drivers including a stolen high performance car with a determined thief at the wheel. The thief is so determined that he risks a head-on crash as he drives the wrong way down the motorway, leaving the cops to launch a city-wide search for him.

The Motorway Cops help stop a stolen lorry on the rampage in the city centre. Elsewhere it's guile which catches people who are economical with the truth.
