The Lady Vanishes

During a snowstorm, a group of passengers are stranded at an inn, waiting for the railways to be cleared so they can continue their journey to the United Kingdom. Young Iris befriends the enigmatic Mrs. Froy, who mysteriously disappears when the train resumes its journey — and the other travelers deny that she ever existed. With the help of Gilbert, a musicologist, Iris tries to uncover the truth. The international success of this Hitchcock film, voted by the BFI as one of the best British films of the 20th century, cemented the director's prestige and paved the way for his transition to Hollywood.
