Man and Woman (1920)

Bradley, an engineer, becomes a Tahiti beachcomber after the collapse of a bridge he built. Murdock, a former employer of Bradley, arrives on the island with his lovely daughter Diana, who wagers with a guest of the governor-general that she could dress the lowest outcast in good clothing and pass him off as a gentleman. She chooses Bradley, who finds out about the hoax and, determined to teach her a lesson, takes her to Leper Island where she is treated like an outcast. Murdock recognizes Bradley and offers him a chance to redeem himself by overseeing the repairs made on a lighthouse. Diana, having now understood Bradley, remains on Tahiti with him.
