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.
