Synopsis by Janiss Garza
Bruce Donaldson (Guy Coombs) is an inventor who has developed a diving bell. He is in love with Ethel Walling (Rubye deRemer), but when his nephew Tony (James Morrison) comes on the scene, he lets him have the girl. Wanda, a vampire from Tony's college past (Christine Mayo) begins to blackmail him when he and Ethel become engaged. Tony goes to his uncle's house to borrow money. His friend, Mark Hornback (John Reinhard), meanwhile, steals Bruce's plans. Bruce finds out that Wanda is the cause of Tony's difficulties and offers to "compromise himself" (as they said in the 'teens) with her to save his nephew's engagement. But it turns out that Ethel really loved Bruce all along, so Tony graciously steps aside so that they can be together.
