Her Body in Bond (1918)

The cabaret act of husband-and-wife dancing team Peggy and Joe Blondin is broken up when Joe becomes consumptive and is ordered West to recuperate. Peggy remains in New York to maintain the couple's income but gradually becomes desperate when letters sent her by her husband request more and more money. Joe's letters actually are being intercepted and rewritten by millionaire Harlan Quinn, who has designs on Peggy and wishes to portray Joe's situation as hopeless. After receiving a particularly alarming letter, Peggy consents to sell her honor to Harlan.
