In 1920, noted archaeologist Sir Basil Walden leads an archaeological expedition in search of the tomb of Prince Kah-to-Bey. Included in his party is Paul Preston whose father Stanley Preston has financed the expedition. When they're more than a month overdue in returning to Cairo, the bombastic elder Preston arrives and soon finds them just as they've located the tomb. After finding the young Prince's remains, the mummified remains of Prem, Kah-to Bey's servant, comes to life to seek revenge against all of those who desecrated his master's tomb.—garykmcd
