As Pcs Mel Ryder and Sergeant Smith patrol the streets on a busy New Year’s Eve, Mel admits she’s worried about her brother, Jordan, and his girlfriend, Kelly Skipton, who have come down to London to see in the New Year at Trafalgar Square.

But Mel gets an even bigger shock when she sees Smithy arresting a young man for the stabbing – her brother, Jordan. In custody, Mel and Jordan begin to argue – but Smithy warns Mel she must remain impartial to help Jordan.

But at the stroke of midnight, the alarms go off on Josh’s life support machine and Mel realises her brother could be in big trouble…
