Near the end of a busy Bank Holiday weekend, biker cop Paul Buckley is called to a serious crash involving a car and motorbike in the North Yorkshire countryside. Tragically, the biker has died. Paul and colleagues begin piecing together how and why the collision occurred to work out if either the driver or rider could be to blame. Near York, after a disqualified driver fails to stop for police and goes off road and on the run, biker cop Paddy Green hunts down the runaway driver.
