While her parents are studying an ancient settlement in Italy, Reeya Rai and her friend Finlay discover a nearby cave. Inside, they find evidence that a priceless, jewel-studded figurine of an ivory peacock may be nearby. Excited, Reeya and her family decide to explore the cave, where they find the priceless artefact hidden deep inside. But there's one problem: it sits on a ledge across a wide crevasse that's too far to jump across. Even worse, their rival, Dr Acker, is also searching the caves for the precious figurine. Will Reeya invent something to safely retrieve the ivory peacock before Dr Acker finds it?.
