Season 1

Dom and Kay, two ordinary PCSOs, are recruited by Detective Inspector Clinton Blair to go undercover and infiltrate the infamous Brightmarsh Gang.

Dom and Kay have a body to bury. They’re in a mess, frightened and completely on their own. Who else knows about their mission, other than Clinton Then, they bump into fellow PCSO Pricey in a 24-hour café, who doesn’t quite believe Dom and Kay’s story as to why they are caked in mud.

Dom and Kay fail to meet the Brightmarsh Gang’s deadline for a drugs payment. Can Dom persuade Kay to steal from the church, or will Kay’s faith mean they get their legs broken?

Dom and Kay track down a new, potential undercover contact called Kirsty. Can she get them out of the Brightmarsh Gang?

Posing as volunteers, Dom and Kay visit Riverford Residential Home, suspecting it could be a front for the Brightmarsh Gang.

After Kay tails Celia Herrington’s mystery visitor to a 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 - after an attempted raid on Dom’s parents’ house.
