The other side of the door

In 1865 San Francisco, young Ellie Fenwick is out shopping early one morning. On her way home, she detours down Dupont Street. As she is passing by a notorious gambling parlor, she hears a gunshot. A man falls through the door into the street, dead, closely followed by another man, Johnny Montgomery, holding a smoking pistol in his hand. At Montgomery's murder trial, Ellie's testimony helps to convict him. But Ellie remains unconvinced of his guilt and when a mysterious "Spanish Woman" interferes with the course of justice, Ellie is torn between her feelings for Johnny and her desire to do the right thing.
