Clementine Hetherington and her robot brother, Digory, have run away from the orphanage they have been living in since their parents died. Clem and Dig want to follow in their famous archaeologist mothers footsteps, but no one will take them seriously. Their chance arrives when a man from their past saves Digorys life, and to repay the debt they enter a multiday rally race... to recover stolen artifacts! Clem and Dig hope to win so they can give the artifacts to a museum, but their opponents want to sell them on the black market. The Ironwood Race has no rules, and Clem and Dig might be in over their heads!
