It's Saturday night in Luton, and Bedfordshire Police are dealing with drunken domestic disputes and a booze-fuelled fight. Police Constables Leanne Turner and Andy Parsons are sent out to investigate an alleged assault against a vulnerable and fragile 75-year-old man in a domestic dispute. The suspect is the man's private carer and has been living with him for the past seven years. When he made the 999 call, the elderly man alleged that he had been slapped in the head with an open palm. But when they arrive, PCs Leanne and Andy are confronted with a distressed victim who insists he does not want them to pursue the matter and who begs them to leave. At the police station, a Polish man arrested for a drunken row with his partner is admitted into custody.

On the surface, two very different cases, but both officers turn the cases they are investigating into something of a crusade and are determined to get to the bottom of what really went on in the private relations between their suspects and the victims.

This episode opens with a young man accidentally dropping a large quantity of cocaine from his jacket pocket outside a petrol station - all caught on CCTV. On the case are hard-bitten Detective Constable Colin Knight and fresh-faced Police Constable Oly Tomlinson, who joined the team three months earlier. They get off to a promising start, tracking down the owner of the vehicle the passenger was travelling in. DC Knight brings in his chief suspect for questioning and discovers that, just like the man in the CCTV footage, he has a striking tattoo on the right side of his neck, but could it be a case of mistaken identity? Also brought in to the custody suite is Darren, a man arrested on suspicion of theft of meat from Marks & Spencer. As he is booked into custody it soon becomes apparent he is a heroin addict.
