女性不能觀看奧林匹克運動競賽!古希臘的確有這項規定。當神奇樹屋將傑克與安妮帶到古老的希臘時期時，他們發現了這個不合理的現象。安妮要傑克自己去觀賞那些比賽，而傑克猜想安妮的心裡一定在打什麼主意。安妮能夠想到去觀看比賽的方法嗎?還是她不只會讓自己麻煩上身還會拖累傑克呢?想找出問題的解答唯有在第十六集的故事中喔!
為了拯救第四個失落的古老故事，這一回，神奇樹屋帶著傑克與安妮回到奧林匹克運動會的發源地--古希臘。
原本以為這次的任務很順利，因為才離開樹屋，他們就遇上舉世聞名的哲學家柏拉圖，並且在他引領下，找到了失落的故事。只是既然到了古希臘，又碰上四年一次的奧運會，沒有理由不留下來看比賽的道理，但沒想到，這竟然令安妮身陷險境！只因為她是一個女孩！在警衛層層的包圍下，傑克該如何救出惹上大麻煩的安妮？他們能安全的把失落的故事帶回去給摩根嗎？他們還有下一次任務嗎？
