The long lane's turning (1919)

When brilliant lawyer Harry Sevier, an alcoholic, cannot cope with the prosecution's tactics, his innocent client Paddy the Brick goes to prison. After Harry's sweetheart Echo Allen, the daughter of Judge Beverly Allen, breaks their engagement, Harry leaves to combat his problem. Meanwhile, Cameron Craig, whose interest in a distilling corporation is threatened when a suit is brought before Judge Allen, steals incriminating love letters written by the Judge years earlier. Echo boards a train to offer to marry Craig for returning the letters. Harry, on the same train, and now beardless, follows Echo to Craig's home, where a burglary occurs. After Harry, not recognized by Echo, gives her the letters, Craig is shot, and Harry, along with Paddy--now a burglar--is sent to prison. Harry escapes and finds himself nominated to run for governor on the "dry" ticket. After Echo confirms that he was innocent of shooting Craig, Harry wins the election and her love.
