When Rip's former girlfriend, Dr. Anderson, steals an Egyptian sarcophagus, hoping to clone an Egyptian Princess inside, the team must fly to Iceland to get it back. But before they can, a British curator feels compelled to reveal a secret his museum has been keeping for over eighty years. The mummy was removed from the sarcophagus and smuggled aboard the Titanic. Fearing the sinking of the great ship would be blamed on them, they never revealed the sarcophagus was empty! When Dr. Anderson discovers the same, she refuses to believe the story and demands Rip help her locate the missing mummy! But when an electrical failure on her plane causes the empty sarcophagus to plunge into the ocean right where the Titanic sank, Rip can't help but wonder, was the Princess just trying to return to her resting place?
