About Passenger
Passenger is a 2024 British mystery drama created and written by Andrew Buchan, marking the actor's debut as a screenwriter. Broadcast on ITV and streamed on ITVX, the six-part series is set in Chadder Vale, a small and seemingly sleepy former mill town in Lancashire. The story follows Riya Ajunwa, a former big-city detective who has relocated to the close-knit northern community, where the slower rhythms of small-town policing are upended by a sequence of strange and inexplicable events. When a young woman vanishes, Riya is drawn into an investigation that resists the tidy explanations she once relied upon.
Wunmi Mosaku leads the ensemble as DI Riya Ajunwa, an outsider whose sharp instincts and methodical approach set her apart from a town that would rather look the other way. As the disappearance widens into a web of unsettling occurrences, Riya finds the boundary between rational explanation and something stranger growing harder to police. The series carries a light supernatural edge, using folk-horror atmosphere and the brooding landscape around Chadder Vale to keep both the detective and the audience uncertain about what is really happening beneath the surface of ordinary lives.
Across its six episodes Passenger balances a grounded character study with eerie, dreamlike mystery, weaving the secrets of an interconnected community into a single escalating puzzle. Praised for its distinctive tone, dry humour and strong central performance, the show blends the conventions of the British crime drama with the unease of folk horror, asking how a town carries its buried history and what happens when the past refuses to stay hidden. It positions Riya as a newcomer who must earn trust while confronting events that defy the explanations everyone around her would prefer.
