Interceptors Alex and Josh head to HMP Five Wells, one of the biggest category C prisons in the UK. A man's been seen tossing suspicious parcels over the prison wall and when the boys arrive at the car park, they clock someone acting shifty in a hire car. Thousands of pounds worth of drugs destined for prison are seized in an instant. ANPR directs Callum and Rachael to a motor that's linked to drug offences. When they stop the car, its driver tosses bags of drugs into the boot and his mobile phone over a wall. But a more bizarre act follows. Stewart and Callum pull over a middle-aged driver whose motor appears not to have any insurance. The man of mystery provides two different names and two different dates of birth.

A pair of potential car thieves are chased by pursuit units and drone, then nicked by police canine Rocky and the firearms squad. The couple caught in separate stolen cars have the honour of being busted by half the force. The Dog Unit are called to deal with reports of a man stealing fuel from parked vehicles - and the suspect is found cowering behind a water butt. Bomber drops a stinger on a van with cloned plates. It's a direct hit with the bed of nails and the unlicensed van man is soon brought to a standstill.
