Still guilt-ridden about the destruction he caused while he was Zod, Lex (Michael Rosenbaum) throws a charity costume ball for the town and hires the All-American Rejects to perform.

Meanwhile, Clark (Tom Welling) and Chloe (Allison Mack) pursue a creature who uses male human bodies as potting mix to procreate, and the hunt intensifies after the creature gets hold of Jimmy Olsen (guest star Aaron Ashmore). Lois (Erica Durance) reluctantly agrees to be Oliver Queen's (guest star Justin Hartley) date to Lex's ball.
