Captain Caveman & the Teen Angels

Lani and Rick's wedding is about to be cancelled when the famous Manipoa pearl--given to Lani's parents by Rick's parents to end the feud between the Kehemas and the Palis--mysteriously disappears. Cavey and the Teen Angels volunteer to help their friends, and they discover that Rick's brother Dan stole the Manipoa pearl, knowing that the theft would stop the wedding and give Dan the chance to win woman he loves: Lani. Cavey and the Teen Angels accidentally break through the time barrier and are transported back the prehistoric era. Delighted, Cavey introduces the Teen Angels to his parents, but he discovers that his father, the tribal chief, is to be dethroned by the evil Gort. Cavey and the Teen Angels go into action to reveal Gort's underhanded intentions to the High Priest--and Cavey's father retains his rightful throne.
