If you had a chance to fix a mistake from your past, would you take it? Alyson Levy would. Guilt weighs heavy on former criminal wheelman Alyson, who led an illicit life that left her shattered. Enter Casper Quellex, an eccentric businessman who offers her the break of a lifetime: a massive cross-country car race that grants the winner an opportunity to correct a single mistake in their life. But here's the catch--each leg covers a different period in history. Just like that, Alyson and the other drivers find themselves in a gut-wrenching race through time contending with medieval warriors, dinosaurs, and natural disasters where they quickly learn that they must band together to form any chance for survival. But for an opportunity to change history, Alyson will drive from the Big Bang to the death knell of the universe.
