The growth of small-town juvenile crime starts a movement for the construction of a youth center. The project leaders discuss with town mayor Phineas Wharton Sr. about buying an old warehouse and rebuilding it as the Center. However, Wharton has plans to buy it himself for another project from which he would profit. But the Teen-Agers--Freddie, Dodie, Betty, Lee and Roy--now attending San Juan Junior College, think otherwise.

The stooges are janitors working in a movie studio. After wrecking the bosses office, they get jobs as actors in an African movie. Curly plays a gorilla and Moe and Larry are primitive natives. On location in Africa, the stooges have a confrontation with a witch doctor from whom Curly buys some "love candy" with hopes of attracting the films leading lady. When a female gorilla disrupts the movie set, Curly eats some of the candy and chases after her.

The stooges join the "Women Haters" club and vow to have nothing to do with the fair sex. Larry marries a girl anyway and attempts to hide the fact from Moe and Curly as they take a train trip.

To escape the police, the stooges pose as plumbers and are hired to fix a leak in a fancy mansion, but they wind up crossing the electrical system with the plumbing and generally ruin the place.
