The Jetsons Meet the Flintstones

In the space age, Elroy Jetson works on a time machine, devoting long hours to perfecting the device. His effort sets the stage for inter-era adventures that will bring the Jetsons and the Flintstones into contact. The project looms as the central catalyst for the story's time-travel premise.

Mr. Spacely suspects George Jetson of industrial espionage and orders him to spy on rival Cogswell. George agrees, hoping to clear his name and save his job. He soon uncovers a scheme where Cogswell's S.A.R.A. seduces Spacely's R.U.D.I. into leaking secrets, and R.U.D.I. sabotages his attempt to report it.

In Bedrock, Wilma and Betty urge Fred Flintstone to arrange a vacation to Honolurock, hoping for a break from routine. Fred brushes off their pleas and remains focused on work. The push for time off creates a rift between him and his family expectations.

Fred explains his vacation idea and the upcoming poker tournament at the Water Buffalo Lodge to Barney. Mr. Slate orders them to work the late shift instead of vacationing. Disobeying orders, they sneak to the lodge to gamble and prove themselves, hoping Turk Tarpit is beatable.

Fred faces off with Mr. Slate in a poker match and loses, while Barney is exposed as an accomplice. A spider reveals their deception, and both Fred and Barney are fired from their jobs. The incident cements a turning point in their circle of friends and bosses.

Back in the future, Elroy finishes the time machine-making project, signaling a turning point for the Jetsons. The Jetsons decide to use the device to travel to the 25th Century for relaxation. The idea sparks a cross-era journey that will intersect with the Flintstones' world.

During a camping holiday, the Jetsons crash into Bedrock and meet the Flintstones and Rubbles. Fred is fascinated by George's gadgets and begins to see an opportunity to help Mr. Slate with future tech at a company picnic. The two families quickly form a friendship that transcends time.

George and Fred use future technology to assist Mr. Slate in the games at the upcoming company picnic, earning trust and a potential path back to their jobs. Turk Tarpit's cheating has set him back, giving Slate reason to rely on the newcomers. In the final event, Astro and Dino's antics tilt the win away from Slate, and Fred and Barney are fired again.

Stuck in Bedrock, George asks Mr. Slate for a job. Slate initially refuses, but Turk Tarpit offers George work, and Slate promptly makes him a partner. George's rising status brings him fame and a new foothold in Bedrock's economy.

The Jetsons' fortune climbs as they acquire several local businesses, leaving them briefly overwhelmed by success. Mr. Spacely, worried about competition, uses Fred as a spokes-caveman for his own ventures, and tensions rise with R.U.D.I. and S.A.R.A. The rivalry between Spacely and Cogswell grows in the background.

Rosie asks R.U.D.I. to help Henry Orbit repair the time machine so the Jetsons can return home. S.A.R.A. appears and demands that R.U.D.I. get rid of Rosie before she departs. R.U.D.I. agrees to help the Jetsons and parts ways with S.A.R.A. for good.

R.U.D.I. and Rosie repair the time machine, enabling a path home. Rosie is transported to the Stone Age to locate her family, reuniting with the Flintstones and Rubbles along the way. The moment marks a tentative bridge between the two eras.

The Jetsons prepare to leave for home, taking Fred's car with them. Judy says goodbye to teen idol Iggy, while Spacely schemes to turn Fred's car into a futuristic product, and Cogswell sends his robotic dog Sentro to steal the time-travel data. The corporate battle lines begin to converge once more.

Astro and Dino join the effort to stop Sentro and destroy the gathered evidence. Spacely secures a sale of a Stone Age car to Cogswell, then warns him not to copy the design or face a legal challenge. The rift between George, Fred, and Barney is tempered by new partnership deals.

Elroy reveals the time machine is broken beyond repair. Fred's car absorbs the time machine's quadra-potents, so the Jetsons return to the Stone Age. The Flintstones and Rubbles bid the Jetsons farewell as they return to Bedrock.
