Two community police officers: Dom (Gbemisola Ikumelo) and Kay (Hammed Animashaun) are persuaded by DI Clinton Blair (Ariyon Bakare) to get fired from their jobs and to go under cover to penetrate a drug gang on a East London estate.
After being forced to bury a body, Dom and Kay break in to DI Clinton's house to try to find out more about his investigation. While they're there, someone else breaks into the house.
Dom and Kay are given a large package of drugs to sell for the gang. While trying to shift the goods, they have their package robbed, and now they have to somehow find £3,000 before the gang's deadline for settling the deal passes.
Could Kirsty be an undercover contact and just the person to get Dom and Kay out of this mess? They arrange to meet Kirsty and set about investigating the seemingly shady superintendent Edwards by breaking into her office.
Dom and Kay realise that the lady they saw Edwards visit at an old people's home is not her mother, and suspect the home may be a front for the gang. Meanwhile, Tevin grows suspicious of the pair after following them a Police Station.
After Kay tails Celia's mystery visitor to an Ministry of Defence building, Dom is convinced that Kirsty will no longer be able to ignore their pleas for help. But first, they must hide Clinton's dossier somewhere safer.
