Phil is a fish who lives in the sea with his family but doesn't like going to school. One day while playing, Phil eats a worm with a note that says it's dangerous, and gets caught by a fisherman. The fisherman puts Phil in a tank, where he is sad and misses the ocean. The fisherman tells Phil to go to school to learn to read so he can be free. Phil goes to a tiny school for fish, learns quickly, and earns stickers for his scales. Once Phil knows how to read and write, the fisherman releases him back into the sea where he is happy to be with his family and friends again.
