Weakchin, the tramp, falls asleep on a park bench, and presently is dreaming of the days of his prehistoric past. He finds himself in an ancient kingdom, flirting with one of the water carrying maidens of the King. Presently he is set upon by Cleo, the King's fool. Then the King comes and the fighting becomes hilariously funny. In the end Weakchin and the King become great friends, but the King's jealousy of Weakchin's attention to his favorite makes trouble. Weakchin throws the King over the cliff, and reigns as King himself. The old King, rescued by Cleo, returns and beats Weakchin over the head. He wakes to find a policeman clubbing him and telling him to "move on."
