The Key to Yesterday 1914

George Carter, a revolutionist in South America, is the exact double of Frederick Marston, a famous artist in Paris. Carter is betrayed by a comrade and is sentenced to be shot. He takes a desperate chance and escapes on board a vessel bound for London. In Paris Marston is stabbed by a model because he does not return her love. The wound incapacitates him from painting, and leaves an ugly scar, and he goes to America on a vacation. Highwaymen attack him, inflicting injuries which cause a total loss of memory. The robbers leave nothing in his pockets but the key to his Paris studio, and Marston adopts the name of Robert Anglo-Saxon.
