Dragon

Days before Lex Luthor's big party, Clark's wishes come true when Lana unexpectedly leaves her boyfriend. Then suddenly Clark's powers and his memories of them vanish. At the same time a paroled killer named Ray Dansk returns to Smallville, where meteor contaminated water gives him the fierce strength of a dragon and a rage to pay back the town that sent him to prison. Unless Clark's memory and abilities return, Lex's mansion will become the place where a villian's vengeance will be carried out on the people of Smallville.
