Inspector Anton Sullivan is on the hunt for an escaped prisoner who is believed to be a high risk to the public, with a drone and dog handlers helping in the search. Anton is then called to a serious collision on the M56 involving a motorcyclist and multiple vehicles, while PC Niaz Waddington deals with boy racers who are weaving through traffic and speeding on the motorway.

PCs Matt Turner and Ian Cosgrove pull over a van they suspect is on cloned plates. During questioning, it becomes clear the driver has more to hide.
