The sequel to 1934's The Notorious Sophie Lang, The Return of Sophie Lang once more stars Gertrude Michael in the title role. Before reforming, Ms. Lang was a jewel thief; now she is the scrupulously honest traveling companion of an elderly dowager (Elizabeth Patterson). When the old lady's diamonds disappear during an ocean voyage, suspicion immediately falls upon Sophie. The ex-thief turns amateur sleuth, tracking down the guilty party in order to escape incarceration. A young but very self-assured Ray Milland provides the romantic angle in The Return of Sophie Lang.
