The manager of a new hotel is in trouble--it's opening day and his staff has quit, including the plumbers who have yet to install any bathtubs in the rooms. As angry guests keep demanding rooms with a tub, the manager's janitor tells him of someone he knows who has invented the 'automatic bathtub'--just what the manager thinks he needs to keep his guests happy. However, the inventor hasn't quite gotten all the 'bugs' out of his invention yet. Complications ensue.
