When Lex Luthor loses a $150 million contract to Luthor Corp, he finds that his mansion was bugged by his father. He hires a team to bug the offices of Luthor Corp expecting to find the building empty since it is Sunday, but Lionel Luthor assigns Martha for work in his office with him. Jonathan becomes very upset, since it is their wedding anniversary, and he was planning a picnic with Martha. Lex calls off the action, but the leader of the group of industrial spies is killed by a member who wants to steal the contents of Lionel's safe. Martha and Lionel become hostages of the criminals, and when they open the safe, a great secret is disclosed. Meanwhile, Lana schedules a meeting with Mr. & Mrs. Small in The Talon to get to know Jennifer Small, who warns Lana about her husband.

The Kryoptonian metallic disc is returned to Clark following the death of Virgil Swann. Placing the disc in the cave reveals a message from the spirit of Jor-El instructing Clark to find the three Kryptonian knowledge crystals and unite them before others find them and use them to self-interest. The message goes on to tell Clark that allowing a human to assemble the crystals could lead to the destruction of Earth. The first stone, retrieved by Lex in Egypt in the season opener, is in Clark's possession in the cave. The second is apparently in possession of the late Swann's associates. And the third is located somewhere in China. Clark joins forces with Lana where they venture to China to search for the stone where Lex and Jason are also on the hunt for the stone. But they end up captured by the Chinese authorities and tortured for information to the stone's location, and it leads to the spirit of Isobel once again commandeering Lana's body to fight everyone to take the stone for herself.
