The Sleep WalkerMovie

Doris Dumond is called home from a convent school by her mother, who has purchased some diamonds and has sold them although she has paid only one installment of the price. Hammond, the dealer's agent, threatens to have her arrested unless she pays the debt within 24 hours. Doris, who is a somnambulist, enters Hammond's room at night while asleep, and purposely misconstruing her visit, he keeps her there.
