The Lady Vanishes

Classic thriller from Alfred Hitchcock, made shortly before he moved to America. When the elderly Miss Froy (Dame May Whitty) goes missing on a train bound for England, her friend Iris Henderson (Margaret Lockwood) sets out to find her. However, Iris's attempts are immediately frustrated by her fellow passengers, who question whether Miss Froy ever even existed.

Only music scholar Gilbert Redman (Michael Redgrave) is prepared to believe Iris, and together they set about getting to the bottom of the mystery.
