Everyone has a future. Clark Kent has a destiny if he's willing to accept and able to master all the awesome powers and responsibilities that come with it.
The fascinating reinterpretation of Superman mythology and its classic characters continues in an event-packed 22-episode Season 3 that includes Clark's embracing of his dark side... and the devil's bargain Jonathan makes with Jor-El to rescue his son. Other highlights: Perry White and villainous Morgan Edge debut in the series. Clark hones a sensational new power. Chloe lets slip an intriguing reference to someone named Lois Lane. And the secret of Clark's true indentity burdens Pete, obsesses Lex and drives a wedge between Lana and Clark. The challenges of today shape tomorrow as never before in Smallville.
