The Girl from Nowhere.

Headstrong Mavis Cole defying her grandfather runs away with the wealthy but caddish Herbert Whitman. Proving he’s no good Herbert plants a stolen necklace on Mavis and attempts to have her arrested when he comes under suspicion, so Mavis flees to a hunting lodge then entering into a marriage of convenience with Jimmy Ryder to hide her identity. Meanwhile, Herbert bribes ex-convict Steve La Marche to steal a jewel from Dorothy Grosscup but Jimmy captures the thief, though he claims innocence. Dorothy accuses Mavis of the theft, but she is cleared by Steve, resulting in Herbert's arrest.
