Across six parts, Passenger follows a Former Met Police Detective called Riya Ajunwa (Wunmi Mosaku) as she investigates a series of strange crimes in the fictional small Northern town of Chadder Vale.

Riya is listless. She first arrived in the declining town five years ago and has been searching for that 'one big crime' that will revitalise her career ever since.

Then one night a local girl, Katie Wells (Rowan Robinson), mysteriously disappears. She reappears the next day ostensibly safe and sound, but for Riya, if not the locals, none of it sits right.

While the disappearance sets off a chain of strange happenings and increasingly shocking crimes in the town, Riya comes up against the residents resorting to parochial theories and blaming outside influences such as the fracking site and its manager Jim Bracknell (David Threlfall).

Jo Hartley (After Life) will also star as Chief Constable Linda Markel, Sean Gilder (The Gold) as Tony Corrigan and Debbie Rush (Coronation Street) as forensic analyst Terry Jackson.

They will join the already announced ensemble of Daniel Ryan (The Bay) as Derek Jackson, Barry Sloane (Six) as Eddie Wells, Natalie Gavin (Gentleman Jack) as Joanne Wells, Nico Mirallegro (My Mad Fat Diary) as Kane Jackson, Hubert Hanowicz (This Is Going To Hurt) as Jakub Makowski, Jack James Ryan (Coronation Street) as John Trowbridge, Matilda Freeman (Alma’s Not Normal) as Lilly Wells, Shervin Alenabi (Baghdad In My Shadow) as Mehmet Shah, Ella Bruccoleri (Call The Midwife) as Ali Day and Arian Nik (The Bay) as Nish Chowdry.

Lee Haven-Jones (The Bay) and Nicole Charles (The Following Events are Based on a Pack of Lies) will direct the series.

Passenger will premiere on ITVX in 2023 and will also air on ITV1.
