The Flinstones is about a modern stone-age family, set in the prehistoric times. There's Fred, the meat-loving, bowling-playing fat man, Wilma, his wife who loves to cook and Pebbles, their cute baby daughter. Their next door neighbors are Barney, Fred's best friend, Betty, Barney's wife who always loves to hang out with Wilma, and their baby son Bamm-Bamm who is incredibly strong. The two families risk prehistoric danger or wild antics as they struggle to live normal lives.
Fred fakes illness so he and Barney can get out of taking their wives to the opera. Using prehistoric helicopter as a means of escape, the two of them join their bowling team for a night of fun. They almost get away with their scheme, until loose-lipped Barney gives away their night's activities.
Believing he has made Wilma and Betty disappear through magic, Fred capitalizes on his newfound freedom by taking Barney to a nightclub, the Rockland, where an old friend, trumpeter Hot Lips Hannigan, is performing. The jazz is cool until the wives show up to teach their wayward husbands a lesson.
Fred and Barney jointly build a swimming pool, but Barney hogs the pool time, angering Fred. To get even, Fred hires a pal to pose as a police officer and break up one of his neighbor's pool parties.
Fred uses his influence with a business friend to obtain a job for Barney, who becomes a furniture repossessor. To the dismay of both, Barney's first assignment is to repossess Fred's television! Unwilling to betray his friend, Barney pays off Fred's delinquent television bill with his first paycheck.
A conk on the head turns Fred into an aristocratic sophisticate, whose behavior manages to disrupt the entire city of Bedrock.
Roped into babysitting little Egbert, the child of a friend, Fred and Barney take the tot over to the pal Joe Rockhead's house to watch the fights on television. Egbert befriends Joe's pet runtosaurus and dresses the creature up in his baby clothes, which results in chaos when the pet--whom Fred and Barney mistake for the baby--escapes from the house and dashes up a tree.
To finance their dream of opening a pool hall, Fred and Barney visit the dinosaur racetrack where Fred bets his entire paycheck on a long shot. He tells Wilma that he has lost his check. When the long shot pays off, Fred and Barney are initially elated, but they quickly realize their problems are only beginning.
