The episode starts with Nobita getting home and wanting to go to Shizuka's house to play, but is stopped by Doraemon. He then open a book and tells Nobita that if he goes out, he will get in hospital because he will be hit by a truck. After persuasion by Shizuka, Doraemon goes outside with Nobita and uses a "future mirror" to see what will happen to them in 10 seconds time. Eventually, after near-accidents, they make it there but when he opens the door he gets hit by a toy truck on the head. The episode ends with Nobita laughing with Doraemon. First use of flying hats.
