About Unforgotten
London's cold case unit returns to life when a string of decades old mysteries resurfaces. DS Sunny Khan leads a task about missing persons, killings, and secrets that refuse to stay buried. Each investigation crosses lines between ordinary lives and the quiet pain left behind by time and secrecy. As new evidence surfaces, memory becomes a central player, tugging at families who think they know what happened and others who prefer to forget. The team must balance speed with sensitivity, revisiting old files, interviewing reluctant witnesses, and confronting the way the past can reshape present loyalties. The team balances duty with personal cost, threads running through every case.
Directed by Andy Wilson and created by Chris Lang alongside Gwen Gorst, the series debuted in 2015. The investigation driven drama benefits from a tight production team and a grounded, contemporary London setting. It features a strong ensemble led by Sanjeev Bhaskar and Sinéad Keenan.
The series stands out for its humane take on crime investigation. Sanjeev Bhaskar anchors the show as Sunny Khan with warmth and resolve, while the ensemble threads together personal histories that complicate justice. It has helped shape a thoughtful British crime drama voice. Its use of London locations and working class voices gives texture beyond the standard procedural.
Critics have praised the series for balancing procedural rigor with character driven storytelling. Themes of memory, guilt and the pursuit of truth recur across cases, challenging assumptions about justice. The show invites viewers to weigh small city secrets against the needs of the living.
