While happily roller skating, Woody (Grace Stafford) gets bullied by an angry Buzz Buzzard (Dal McKennon) who has just avoided being served a summons. Thinking the woodpecker might want to seek mild revenge on Buzz, law officer I. Gypem (also McKennon) tells Woody he will pay him a dollar to serve Buzz with the summons.
Woody happily accepts the offer from Gypem, but Buzz manages to stop all attempts at delivering the summons. Woody then stumbles on a book about hypnotism, which declares: "Influence others and be their master". Woody reads the book cover to cover, and then decides to "practice" his newly acquired skill on Buzz. At first, he has some fun by putting the reluctant buzzard to sleep. Then, Woody turns him into a dog, a monkey, and appropriately enough, a woodpecker.
Finally, Woody blindfolds himself, begins walking on a skyscraper skeleton and tells Buzz (who has been fitted with Woody's roller skates), "I am your master. You must protect me at all times". The two encounter several death defying close calls before Woody manages to secure Buzz and escort him to I. Gypem's office.
Supposedly thankful, Gypem has the audacity to serve Woody with a summons, accusing the woodpecker of "practicing hypnotism out of season". Incensed, Woody hypnotizes Buzz into thinking he is a hungry giant and Gypem is a tasty ham sandwich. While Buzz chases Gypem out of the office and into the city, Woody celebrates his victory by throwing the money into the air and doing his trademark laugh.
