When a wave of insomnia affects the citizens of a town called Pleasant Valley, Cheer Bear, Grumpy Bear, Funshine Bear, and Bedtime Bear go to investigate while trying to help two children named Barbara and Gary fall asleep. When Bedtime discovers that there is no sand on their faces, he surmises that something must have happened to the Sandman, and the crew heads to his home. Finding the Sandman knocked out by his own sand, they soon learn that he has been robbed and quickly travel to the office of the Night Mayor, Pleasant Valley's night shift leader. Not only does he reveal that he was the one behind the pilfering, but he sics his pet Drizzly Bear on them, who promptly summons a rain cloud to wash them away.
