With only three days left before a drastic climate event, a family races to secure resources at their crowded old home. The father stores 50 tons of coal and bricks up the windows, while struggling to legally stockpile diesel. He contacts an old acquaintance, Joe, who delivers the fuel secretly at night, risking exposure when a neighbor notices the diesel fumes. Despite the close call, they manage to fill the underground tanks. As they settle with enough supplies to last three years, a sudden emergency weather warning reveals global temperatures will soon plummet, leaving their survival efforts hanging in the balance.
