Ten-year-old friends, Matthew and Nikki, attend a workshop on Ancient Egypt at the local museum during the school holidays. But when they try on hidden Egyptian gold jewellery, they're transported back to Ancient Egypt.

Their adventures begin when they meet Nephta, a relative of the new Pharaoh. Someone in her household is planning to steal the jewels from the previous Pharaoh's burial tomb and Matthew and Nikki end up in danger, while their bully of a classmate nearly becomes a mummy.

Will Matthew and Nikki escape from the pyramid in time?
