When he fails to reach home by his curfew, Misae punishes Shin by making him sit out on the porch, causing him to miss out on "Action Mask". Shin tries all sorts of ways to get into the house, until he discovers a loophole and goes to watch it at Nene's house instead.
All the food containers fall on the ground because of Shin-chan, so Kazama makes an excuse, but later realizes there is more food.
Misae takes Shin-chan to the dentist to get his cavities treated. After coming home, he continues eating junk food, which annoys her.
Shin chan vuelve a casa tarde y su madre no le deja entrar como castigo. Shin chan quiere ver Ultra-héroe y hará todo lo posible por entrar: hacerse pasar por repartidor, soltar lágrimas de cocodrilo. Kazama, Masao y Shin chan son los responsables del almuerzo. Desafortunadamente, se les cae el estofado y deciden devolverlo con el recogedor a la olla. Shin chan tiene una caries y Misae lo acompaña al dentista. El dentista acaba siendo una mujer muy guapa con la que Shin chan intenta ligar.
