Lana Lang (Kristin Kreuk) is convinced that she is being visited by the ghost of Emily Eve Dinsmore (Jodelle Micah Ferland), a childhood friend who drowned at the age of ten. In his efforts to determine if Lana is actually having a paranormal experience or if she is merely imagining things, Clark (Tom Welling) uncovers a horrible secret about Emily's family -- one that blazes a trail leading right to Lionel Luthor (John Glover). Meanwhile, Lionel's son Lex (Michael Rosenbaum) prepares for his marriage, and Clark's adoptive dad, John (John Schneider), nervously awaits the birth of his new child. ~ Hal Erickson, Rovi
