Mary Lynde (Theda Bara) is an innocent girl who has grown up in New York's Greenwich Village. One of the artists there, Felix Benavente (Sidney Mason), uses her as model when he paints a portrait of the Madonna for a church.

Theda Bara's vamping is at its most evil here. She plays the Russian Princess Petrovitch, who loves only her pearls. Her husband, the Prince (E.F.

So she becomes an Apache dancer instead.
