While exploring ancient catacombs in Egypt, Reeya Rai and her family discover a chamber hidden behind a large wall of rubble. Inside are several mysterious ancient statues. However, there isn't time to explore the chamber. A large storm is coming that threatens to flood the entire region. Thinking quickly, Reeya and her friends invent a way to transport sandbags and build a wall to protect the catacombs from flooding. When they return, what ancient mysteries will they find hidden in the chamber? And how will they keep Dr. Acker and his daughter, Elsie, from discovering the chamber's secrets first?
