Once upon a time, the world was in chaos as intense sunshine caused extreme heat, reaching 150°F, making it difficult to live. Despite this, a man named Finch, protected by a special suit, explores with his robot Dewey. Using a gadget, Finch determines the sun's strength, while Dewey collects supplies. Finch marks his path to avoid revisiting the dangerous sun-blasted areas. Driving through deserted, devastated towns due to the sun's impact, Finch navigates a harsh world left abandoned by most.
