The Mailman

Also known as Sentinels of the Sea, Assalto à Ambulância Postal, メイル・マン, Navnløse Helte, Postraub auf hoher See

“"A stupendous photoplay immortalizing the lives of unselfish devotion in duty of our brave mailmen—lives of real loyalty, of adventure, of romance!"”

Veteran postman Bob Morley and his son Johnnie are honored for their service to the U. S. Mail Service. When Johnnie takes a position on the Enterprise, he is falsely convicted of theft and murder when the cargo is stolen and the ship's officer is shot.
