This is the story of Juanchu, a boy with great imagination. When he goes to school, he puts on his skates and "shoots" down Echegorri hill. Sometimes he is Sherlock Holmes, on the trail of a murderer; and other times, he is a cowboy on his horse or even a steam train.
One morning, when it was raining cats and dogs on the Basque coast of Spain, Juanchu was pretending to be a sailboat on the ocean, his unbuttoned raincoat flapping in the wind... and he sailed right into a black car, which sent him flying several metres through the air. Juanchu broke his skull and both arms and legs, but as his grandfather reminded him, it could have been much worse.
