King Tut's Coup

Plot:

After a blow to the head, Yale's Egyptology professor once again believes he is King Tut. He mistakes Bruce Wayne's friend Lisa for Queen Cleopatra, and kidnaps her so he can bring her to Egypt as his bride. Batman and Robin soon locate Tut's hideout, thanks to a hidden tracking device. But soon after entering, they are captured by Tut's cronies, and Batman is submerged in a sarcophagus under five feet of water.
