Dr. Zalost, an extremely depressed and misunderstood professor, is incapable of dealing with his sorrowful condition by himself. Overcome by his jealousy of other people’s happiness, he lashes out at Nowhere, firing unhappy cannonballs out of his walking tower and plummets the entire town into a state of depression. To gain happiness, he seeks economic elements from the representatives of Nowhere, but when he does not experience relief, he refuses to undo what he has inflicted. With Muriel befalling the effects of the unhappy cannon balls, Courage ventures into the tower of Dr. Zalost to undo the sorrow of Nowhere and the malevolent professor.
