While moto-crossing with Pete (Sam Jones III), Clark (Tom Welling) falls into a cave and discovers two hidden treasures - ancient Indian writings that hold the key to his identity, and a beautiful girl whom he believes to be his soulmate. Desperate to preserve the writings, Clark pits father against son as he enlists Lex's (Michael Rosenbaum) help to stop Lionel's (John Glover) construction crew from demolishing the cave.
