The main character, Jack, is asked by his grandmother to retrieve a family heirloom from a jewelry store. Meanwhile, the rest of the group including Kim, Milton, Eddie and Jerry, are at the dojo practicing for an upcoming tournament.

As Jack enters the store, he meets a girl named Hayley, who turns out to be a skilled thief. She asks Jack to help her steal a diamond necklace, but he refuses. Just then, a group of masked robbers enter the store. Jack and Hayley work together to defeat the robbers and save the necklace.

Back at the dojo, the group is training when Hayley shows up and asks for help. She reveals that her father was falsely accused of stealing a necklace and is now in jail. She wants Jack and the group to help her clear her father's name by finding the real robbers.

The group agrees to help and they begin their investigation by questioning suspects and gathering clues. Along the way, they encounter a group of attractive and wealthy girls who seem to be interested in Milton and Jerry. However, Jack suspects that the girls may be involved in the robbery and warns the group to be careful.

As they continue to investigate, the group discovers a clue that leads them to a wealthy business man who may be involved in the robbery. They confront him and he denies any involvement. However, they notice that he has a diamond tie pin that is identical to the stolen necklace.

The group decides to sneak into the businessman's mansion to look for more evidence. They find the stolen necklace hidden in a secret room and also discover that Hayley's father was not involved in the robbery.

The group exposes the true culprit and clears Hayley's father's name. As a reward, they are allowed to keep the necklace and they use it to pay for their tournament entry fees.

In the end, the group prepares for the tournament and Jack reflects on the value of honesty and doing the right thing. The episode ends with the group practicing their karate moves and getting ready for their next adventure.
