Pebbles, who now works for an ad agency and Bamm-Bamm, who works in a car repair shop, decide to get married after Bamm-Bamm proposes with a poem, in the middle of the street (after Pebbles mistakenly thinks he was trying to dump her when Bamm-Bamm read her a letter that started "Dear Pebbles"). However, Fred loses the family savings when he bet it on his team, the Bedrock Brontos. Fred tries asking for a raise from Mr. Slate, but is dismissed from his job because of his violent temper.
Fred enlists Barney's help in bringing more money for the wedding, but they fail, losing Barney's money to a real estate con artist and becoming more in debt than before. Meanwhile, Wilma's mother Pearl Slaghoople arrives to help with the wedding. Pebbles and Bamm-Bamm decide to elope in Rock Vegas because of their parents' arguing and fighting. Barney angrily unravels the truth about Fred and Wilma’s nest egg. Wilma, livid at Fred, forces him out of the house. After seeing that even Dino’s mad at him, Fred finally realizes the error of his ways and decides to fix his mistakes. Reconciling with Barney, Wilma, Betty and Pearl, Fred asks Barney to help search for Pebbles and Bamm-Bamm.
Fred and Barney travel to Rock Vegas looking for Pebbles and Bamm-Bamm. They stop at a casino where Barney wins more money. They are attacked by the Wedding Whackers gang after mistaking them for Pebbles and Bamm-Bamm getting married and took a photo of them robbing a newlywed couple. Shortly afterwards they are rescued by Bamm-Bamm for Pebbles. During the chase, the photo of the Wedding Whackers is destroyed, so the four are captured as suspects of being the marriage whackers, along with the real marriage whackers.
While in detainment, Fred reveals all the trouble he has gone through to try to help Pebbles with her wedding ceremony which leads the marriage whackers to reveal to their crimes, to the dismay of the Whackers' mother. Since Barney made a lot of money on his casino wins on the big wheel, they can use it to pay for the wedding, replace their nest eggs and pay off their debts. Fred, Barney, Pebbles and Bamm-Bamm finally reunite with Wilma, Betty and the others. Mr. Slate rehires Fred, and Pebbles and Bamm-Bamm get married, with Fred, Barney, Dino, Wilma and Betty as the happy ones seeing them getting married. Fred gets his job back from Mr Slate and is given a raise after being invited to the wedding. At the end, Pebbles and Bamm-Bamm reveal they are moving to Hollyrock with Barney paying their way with his share of the Rock Vegas winnings, at which Fred gets angry with Barney and they start to fight again.

Syndication
This spinoff movie has aired on Cartoon Network in the 1990s, then ran on Boomerang in the 2000s.
Sequel
Hollyrock-a-Bye Baby was released in 1993. The sequel is considered very difficult to syndicate after its original broadcast and the attempt at releasing it on home media was delayed until 2012, mainly due to the involved suggestive material relating to child birth. However, it eventually aired on Cartoon Network and Boomerang usually as part of Mother's Day special programming in the early 2000s.[6]
