Salaryman, Katei Nobumitsu, wants to enter a grandfather and son home video competition but his father is dead. Moguro offers to provide an old man for the video from the "Silver Bank" of elderly volunteers. The aged Mr Ohkubo fills the position too well, and Nobumitsu's son Tarou wants him to stay on which is against Moguro's rules. Ohkubo then takes ill and Nobumitsu has to care for him for the rest of the man's life.
