Clark and Lois investigate Chloe's apparent murder, but Lois' father, General Sam Lane (Michael Ironside), impedes their progress. Lois suspects that her dad knows more about Chloe's death than he will admit, and Clark discovers that Sam has recently been in contact with Lex. Jason arrives from Paris and convinces Lana to continue their relationship. Suspecting that Chloe is still alive, Lionel sends an assassin -- with the ability to morph his limbs into metallic weapons -- to keep Chloe from testifying against him.
