Joe is a boy just like any other, but with a bigger imagination. Joe lives in an ordinary apartment building in a rather ordinary city. His world is rather gray. But he spends his time imagining a wonderful, colorful world filled with exotic plants and unusual animals.

One day, Joe decides to plant a seed on his balcony. He waits and waits, but nothing happens! Joe gives up and returns to his daily life, but when he least expects it, he sees that the seed has taken root and turned into the most beautiful tree.
