In THE MUMMY'S SHROUD, a small archaeological party unearths the hidden tomb of Kah-to-Bey, unleashing a horrible, murderous mummy. Despite warnings given by the tomb's guardian (Roger Delgado), Sir Basil Walden (Andre Morell) and his party proceed to move the mummy Kah-to-Bey to Cairo, and place him next to his slave and protector, Prem. When the guardian reads aloud the words on the shroud covering Kah-to-Bey, Prem comes to life and wreaks havoc on those who would defile his master.
