An intrepid amputee must pass a test to prove his devotion to his sweetie in this romantic drama. The hero lost his leg during the crash of a navy dirigible. Later he gets a job with a lumber company. He soon falls for the boss's daughter. Unfortunately, the general manager is also interested in her and so requires that the young man pass the notorious "blue vase test" in hopes of stumping the lovesick lad. The test involves retrieving a sketchily described vase and bringing it to headquarters on the railway. The plucky lad succeeds, marries his gal, and becomes the new general manager to boot.
