1x14 - Superman

When a scientist is found dead in the Egyptian museum, his assistant is accused, and later found guilty, of poisoning him. When a colleague of the scientist uncovers evidence that may clear the assistant, he contacts Clark Kent to show him a tablet suggesting the scientist may have fallen victim to a curse of the tomb of King Tush. While investigating the burial vault, the men discover that the tomb was rigged with poisonous needles, but also unwittingly unleash one of the king's giant guards that was buried in the vault with him.
