Four detectives. Four timelines. One body. To save Britain's future, they'll need to solve the murder that altered the course of history first.
E1 · 'You're Dead Already'
In 2023, Detective Hasan discovers a dead body in Longharvest Lane, Whitechapel — while in 1941 and 1890, two other detectives find the same corpse.
E2 · 'Do You Know Who I Am?'
Hasan follows new leads in the present. As Hillinghead reluctantly closes his case, Whiteman goes to desperate lengths to hide involvement in his own.
E3 · 'All In Good Time'
Connections between the cases start to come into focus. Whiteman encounters an unexpected complication; Hillinghead attends a séance.
E4 · 'Right Up the Wazoo'
Hasan discovers she isn't the only detective investigating a murder on Longharvest Lane. In the past and future alike, relationships start to deepen.
E5 · 'We Are One Another's Ghosts'
The past, present and future collide as a set of fingerprints from 1890 are found in 2023. Maplewood uncovers the Commander's true identity.
E6 · 'The World Is Yours'
On the day of the explosion, Hasan does everything in her power to help Elias make a life-altering choice. The others wrestle with their consciences.
E7 · 'Catch Me If You Can'
Elias finally knows what it means to be loved. He creates the family he's always wanted — but Hillinghead has to suffer for it.
E8 · 'Know You Are Loved'
Across decades, the detectives work together to stop Elias from reshaping history. Will words be enough to break the loop and save thousands of lives?
