Walter had a dream that 300 years in the future, the world was destroyed due to pollution, natural disasters, and a lack of resources as a result of human carelessness with the environment. People faced food shortages, contaminated water, and total ecological ruin. The world was set to explode in just 3 days. When Walter woke up, he ignored the message of the dream and continued living carelessly. After 60 years, the nightmare became reality, but it was too late to prevent catastrophe.
