While visiting his uncle and cousin in Egypt, Gabe inadvertently brings a mummified prince back from the dead.

Recently orphaned, a young boy is taken in by his godmother who is shocked to realize that she can see the boy's imaginary friend: a flamboyant, French magician named Bogus.

When a sarcophagus, sent by Jeff's Egyptologist father, arrives at the family home, his sister Kim decides to take a look inside. This proves foolish, however, as opening the coffin brings the mummy inside back to life.
