Experience Stephen Graham’s Powerful Undercover Role in ‘Line of Duty’ Season 5
As viewers are introduced to Graham in Line of Duty Season 5, his character initially appears to be the leader of an Organized Crime Group (OCG), John Dayton, who is deeply involved in large-scale robberies throughout London. During the season premiere, the OCG executes a bold hijacking of a police convoy, resulting in the theft of seized drugs and tragically claiming the lives of three officers. Meanwhile, AC-12’s dedicated officers, Kate Fleming (Vicky McClure) and Steve Arnott (Martin Compston), delve into the investigation of this harrowing incident, uncovering that an undercover officer embedded within the OCG has mysteriously gone silent. After interviewing the only surviving witness, they begin to suspect that the undercover officer could be Lisa McQueen (Rochenda Sandall), due to her decision to spare the last witness.
By the conclusion of the first episode, it is revealed that the undercover officer is actually John Dayton, also known as John Corbett. This revelation adds a captivating layer to Corbett’s character, as the gradual unraveling of his identity draws viewers into a complex narrative. Initially depicted as an antihero, Corbett finds himself navigating the precarious boundaries between his undercover duties and his responsibilities as a police officer. His unpredictable and sometimes menacing demeanor creates a thrilling tension that keeps audiences engaged. Despite being deeply embedded in his undercover role, he maintains a poignant connection to his family, sneaking in calls to his wife, Steph (Amy De Bhrún), and cherishing fleeting moments listening to his children as they sleep. These rare glimpses of vulnerability allow Graham to infuse emotional richness into his character.
As the season unfolds, Corbett makes a daring decision by meeting with Arnott to assert that he is not a corrupt officer. Corbett discloses crucial intelligence regarding an impending raid on a police storage facility, hinting that a corrupt officer—potentially the elusive “H,” a central figure within the series—will be implicated. He suspects “H” could be Superintendent Ted Hastings (Adrian Dunbar) but refrains from revealing the personal history that connects them. The escalating tension between maintaining his undercover identity and grappling with the pervasive corruption within the police force adds a thrilling edge to Corbett’s storyline, providing Graham with a rich opportunity to explore the multifaceted nature of his character.
