On the train ride to visit his grandpa, or Papa, Henri is only interested in his game. But then George the dog steals Henri's hat upon arrival, so Henri makes chase and finds himself in front of a trunk full of hats. Henri tries on each hat . . . and imagines himself a racecar driver, a sea captain, a flying ace, and more! Papa finally catches up to Henri and George, and that's when Henri hears Papa's stories, real stories, about racing, sailing, flying, and more! As Henri heads home, he looks up at the stars and begins to dream . . . of being just like Papa.
