"May the crocodile be against you in water and snakes against you on land. The gods will not accept your sacrifices. You and your descendants will be miserable and persecuted!" - Nefertari's curse

Cousins Bernie and Josh have spent years following in their great-great-grandfather's footsteps as travelers and explorers. Inspired by items and stories from Gramps' life chest, they solved dangerous mysteries and discovered treasure in the Great Wall of China, a diamond mine in Tanzania, a Viking village in Norway and an underwater pirate cave in the Bahamas. When they travel to Egypt, however, it's a different story - their luck seems to have run out. After risking their lives again, they come home empty-handed. Is it time to retire from adventuring? Or will the next generation come forward and take up the cause?

Josh's granddaughter April has been hearing stories of Grandpa Josh and Uncle Bernie's adventures since she was a little girl. Now she's a smart, savvy and fearless young woman, and is ready to join the team.

It's a dream come true for grandfather and granddaughter to go on an adventure together, but the prospect of hunting for an ancient Egyptian city inside a mountain is daunting, and a mixture of magic, curses and life-threatening danger is just around the corner.
