Killing Eve meets Line of Duty as Annie Montague, former DCI with the Met, seeks to track down and apprehend the head of a dangerous and audacious OCG. The group are engaged in the trafficking of drugs and people, as well as money laundering and murder, and everything in between. The boss of the OCG, Mila Romano, is not afraid to make things personal in order to get her way. Annie must ultimately make a choice between bringing her in, and securing the safety of her young son and husband. Following the government's privatisation of the police, and the folding of the Met, Annie also finds herself having to navigate the new law enforcement landscape.
