A peddler who sells caps encounters a mischievous group of monkeys while taking a nap under a tree. When he wakes up, he discovers that the monkeys have taken all the caps from his stack and are wearing them. Despite his efforts to retrieve the caps by shaking his fist and stamping his feet, the monkeys mimic his actions without returning the caps. In a moment of frustration, the peddler throws his own cap on the ground, prompting the monkeys to do the same, allowing him to collect the caps and continue his journey.
