Plot
Fred Flintstone has promised his wife Wilma they will take a vacation. He wants to request days off work and money from his boss Mr. Slate who just then is hiring an indirect relative named John Cenastone. After getting into trouble, Fred is saved by Cenastone. Fred does not receive money from Mr Slate, and Fred does not know how to tell Wilma the bad news. At a fair organized by the Lodge of the Water Buffaloes, Fred devises a way to earn money: he enlistsHoppy, the "kangaroo-saurian" of his friend Barney Rubble, to challenge people to boxing matches. When they arrive, among other attractions are the Boulder Twins who open a kissing booth causing jealousy in Fred and Barney's wives Wilma and Betty.

Hoppy defeats many people, but his winning streak ends when the ruffian CM Punkrock humiliates him. Angered, Barney challenges Punkrock and defeats him. Punkrock exits angrily with his teammate Marble Henry. Fred envisions a great opportunity to earn even more money with wrestling after the success of Barney's performance. They are greeted by a seafood seller named Mr. McMagma and they decide to organize an event at an abandoned circus.

Fred asks Cenastone to recruit more wrestlers. He brings Rey Mysteriopal, a masked clerk; and The Undertaker, a somber gravedigger. The event begins between Cenastone and Mysteriopal, as they are on friendly terms, the fight fails. Fred decides that Barney should wrestle against Undertaker. Barney protests, but Fred presses him. Just when Barney is about to win the match, Wilma and Betty arrive and scold their husbands. Everything is resolved, especially because Fred has earned enough money.

However, Fred aspires to more, inspired by McMagma, and decided to organize a second event. Fred rents the Bedrock Stadium. He promotes a rematch between Barney and Punkrock. Punkrock accepts and Fred also enlists Henry and the Boulder Twins. However, Barney does not agree to participate. Fred leaves without him, starting his show. Mysteriopal and Cenastone fight again, but people are cheering for Barney. Fred announces that Barney will not fight. The other fighters exit, disappointed that Fred has neglected his friend and leaving Fred to face the opponents alone.

Fred takes courage and faces Punkrock and his allies in the wrestling ring, but he is brutalized. Seeing his friend's sacrifice, Barney decides to go and face Punkrock, encouraging other wrestlers to participate. Even Wilma and Betty intimidate the Boulders and Barney and Betty's son Bamm-Bamm easily defeats Henry. Fred and Barney and their team win to great applause.

Fred decides to quit wrestling. He takes his profits and sells the idea to McMagma. At the end, the Flintstones, the Rubbles and the wrestlers enjoy their vacations.
