When it comes to the environment, young Walter is not an enlightened individual. He's a litterbug who believes sorting trash is a big waste of time. What's more, he thinks his friend's birthday present, a tree, is the most ridiculous gift he's ever seen.

Walter believes the future is going to be wonderful, filled with robots and other amazing inventions. One night while lying in bed, Walter wishes he could visit the future. He falls asleep and his wish comes true. But the world Walter sees is not exactly what he'd imagined. When he returns to the present, he is changed and so are his dreams.
