In a frozen wasteland formerly known as Earth, five survivors find themselves stranded on the small island of San Lorenzo. With no hope of rescue, and nowhere else to turn, John, Frank, Newt, Lowe and Hazel, must rely on each other to live. Using the few supplies not ruined by "ice‑nine," the chemical responsible for changing the world forever, they decide that death is not an option. By pure accident, the secret of the antidote to "ice‑nine" is discovered, and the survivors embark on a journey to restore the world and save what is left of humanity.
