The Masterpiece Mystery movie The Lady Vanishes will debut on PBS on August 18 at 9 PM.
The film packs in the suspense and style when Iris Carr (Tuppence Middleton from Inspector Lewis), a beautiful young socialite traveling alone, who befriends a kindly English middle-aged woman but wakes from a nap to find her missing – and all the strangers surrounding her denying that the woman was ever there at all.
This closed-door mystery classic investigates the question of madness and isolation set among increasingly sinister passengers and a train barreling through Europe toward a dangerous and dizzying final destination: the truth.
The cast includes Tom Hughes (Page Eight), Keeley Hawes (Upstairs Downstairs), Gemma Jones (The Duchess of Duke Street), and Alex Jennings (Cranford).
Here is a trailer for The Lady Vanishes (via its original airing earlier this year on BBC One).
