Who's Your Brother? (1919)

Stephen Field, a Jewish financier, takes great pleasure in philanthropic work at a community service center in the U.S. His daughter Esther devotes her time to entertaining returning soldiers in a canteen. When he reads in a newspaper about massacres of Jews and Armenians in Europe, and the suffering and starvation among other peoples there, Stephen remembers having lost his own wife and young son in a massacre years earlier. At the canteen, Esther meets Robert Graham, who suffers from fainting spells, the result of a war wound. Graham falls in love with Esther, much to the chagrin of his anti-Semitic father. Esther is also courted by the brilliant Jewish surgeon, William Morris. Esther's affection for Morris leads the jealous Graham to lash out at his rival with anti-Semitic invective even though Esther gently refuses Morris' marriage proposal. Graham loses control of his high-powered car due to a fainting spell, and the car goes over a precipice and turns over on top of him. Morris is the only person who can save his life, but the surgeon hesitates, fearing that failure would be interpreted as jealousy and thus compromise his professional integrity. Esther pleads with Morris to perform the operation, and he finally consents, sacrificing his own happiness for the woman he loves. The operation is proclaimed a surgical miracle, and Esther chooses to marry the man who performed that miracle.
