Eddie and Maisie are engaged, and have been for a while. They'll get married one day for sure, well, when Eddie earns enough money they will... At Mrs Kennedy's rooming house where they live, Maisie's neighbour, Mirton, pops by to tell her that he thinks he's going nuts. He's been having some dreams, but they keep coming true! The following day, Mirton tells them that he's dreamed about a horse winning the derby... Maybe Mirton's Dreams are just what they need. Maybe the tips from Mirton will help them to raise the money so they can finally get married and settle down...
