The Dawn of Love (1916)

Unknown to his daughter Jacqueline, Miles Allen, in the guise of a fisherman, smuggles silk and fur into the country. Customs officer John Lang comes to investigate, and he and Jacqueline quickly fall in love. Ward Jennings, the owner of Miles' boat, also loves her, but Miles refuses to let him marry her, so Ward gets revenge by revealing Miles' smuggling operation to Coast Guard officers, who kill Miles in a struggle at his home. Jacqueline mistakenly blames John for her father's death and goes to Ward for help. She then learns the truth about Ward; they fight on a cliff-top and he falls to his death. John comes to comfort Jacqueline, and they begin making plans for their life together.
