Alias The Doctor (1932)

Stephan Brenner may be young, but - after his work with a severely injured child and his subsequent efforts with earthquake victims in Italy - he's made a name for himself as a skilled, compassionate surgeon. But it's actually Karl (Richard Barthelmess), Stephan's foster brother, who is the surgeon. And behind Karl's use of his brother's identity lies a sentimental tale of secrets, love and sacrifice.
