The Flash, later shows up at the farm and tries to talk Clark into leaving Smallville for a life on the road together, flexing their super powers. Meanwhile, Lex (Michael Rosenbaum) buys a priceless framed manuscript with Kryptonian symbols and Clark learns that it contains a mysterious hidden map. However, when Bart steals the manuscript from Lex, he inadvertently puts Clark's life in danger and must make the decision whether to save Clark or himself.
