Based on the life of her own grandmother, Luther star Ruth Wilson’s new period drama begins next week.
The “complex tale of espionage, betrayal and polygamy” is written by Anna Symon (Indian Summers).
Dramatising an incredible true story, Mrs Wilson is set in 1960s London, 1940s London and 1930s India.
The cast also includes Keeley Hawes (The Durrells) and Iain Glen (Downton Abbey).
The three 60-minute episodes will air in the UK at 9pm on Tuesday nights from 27th November on BBC One.
Watch the trailer:
The official synopsis reads: “It’s 1963, and Alison Wilson (Ruth Wilson) returns home to find husband Alexander (Iain Glen) dead. Blinded by grief, Alison is bewildered when a woman unexpectedly arrives at the door, claiming to be Alec’s ‘real wife’ Gladys (Elizabeth Rider).
“Alison embarks on a mission to discover who her husband really was. But by dissecting their wartime romance whilst working for the secret service, and learning about his mysterious past in India, it soon becomes clear to Alison that Alec died holding his secrets close to his chest.
“Alison is left craving the truth as she makes discoveries that threaten to tear her carefully crafted world apart.”
Mrs Wilson will air in the USA in early 2019 on Masterpiece on PBS.
