The professor believes that he has found the elixir of life and that with it he can bring back to life even an Egyptian mummy. He buys a mummy from a curio shop. After he leaves, emissaries of the Pasha discover the mummy awaiting delivery and find that it is what they had been looking for, the remains of the Royal Rambastus, 2000 B.C. They are told that the professor has bought the mummy. They offer the professor a big sum for it but he refuses to part with it. Victoria, the professor's daughter, is in love with Eddie. Eddie asks to marry her but is told by the professor that he can have Victoria only in the event that he is able to revive the mummy with his elixir of life. Eddie calls in his chum, Lee. Together they plan to have Lee pose as the mummy. Lee does so, and the experiment proves a success. The Pasha and his men surround the house and await the opportunity to steal the mummy. When Lee is left alone they pick him up and run off with him, pursued by the professor. Realizing that he had got more than he had bargained for, Lee runs away. He seeks refuge in the professor's house, where Eddie takes the real mummy, stabs it and throws it out of the window. The Pasha finally gets the mummy and Eddie gets the girl. The professor is satisfied that his elixir works, and Lee is satisfied that he has proved an able medium for the success of his friend's love affair.
