Two young girls disc jockeys command a sculptor a caryatide to better close the access of their garden against the IBI, intruders-burglars-impostors. Through a mysterious little meteorite of emerald, life is breathed into sculpture which immediately wants to make itself useful to its very first friends. They will probably never see their burglared treasure. But there are other treasures. A jewel had been offered to the young sculptor. Having hidden it too long, this medal has since become the trophy of an Olympiad that is played on the other side of the ocean. But what is this tentacle out of the marine earthquake, which deviates the way of our companions towards a long journey? Does she not resemble the intruder in the garden? Oh dear ! If she arrives in time to play it, what risks the champion to fall in love after the final of the Olympiad? Will there be anyone to forgive her nonsense?
