Pebbles quietly takes things from various stores, but at a jewelry store, a real thief named Baffles Gravel, alias "Lightfingers Leo", plants a diamond necklace in Pebbles' carriage and Fred thinks Pebbles stole that as well.
During a day in downtown Bedrock with Pebbles, Fred discovers that his baby girl is too liberal a shopper, when she fills his cart in the Bedrock Supermarket with candy, crackers, and cookies. While Fred is at Hotrock Jewelers to buy a birthday gift for Wilma- a burlap strap for Wilma's non-existent wrist-watch, said jewelry shop is targeted by Baffles Gravel, a.k.a. Light-Fingers Leo, a suave, mustached, international jewel thief, who, while the store proprietor is occupied with Fred's $1.99 purchase, snatches a multi-diamond necklace from its display case and, knowing himself to be followed by a tenacious pair of detectives, drops the "hot" item into Pebbles' baby carriage for collection at a later time.
Fred and Wilma find the necklace in Pebbles' hand after Fred and Pebbles have returned to cave Flintstone with their acquisitions and assume that Pebbles is a compulsive thief now guilty of grand larceny! At night, Fred and Barney endeavor to reinstall the necklace inside of the Hotrock establishment of business, only to be followed by Gravel, who is constantly under observation by the detectives. Gravel impersonates a Rockland Yard inspector and demands that Fred and Barney, still possessing the necklace and outside of the store, surrender the ring of gems to him.
The true detectives then emerge from hiding and surprise Flintstone, Rubble, and Gravel, assuming the trio to be partners in crime. Fred and Barney plead innocent, and Gravel agrees, as they lack the sophistication to be "in cahoots" with him. Gravel confesses all, and Fred is relieved that his daughter is not a jewel kleptomaniac.
