Japan has a large population that is aging rapidly. A Japanese woman's average life span is 86 years old, which has been at the top of the world record for 25 years. This documentary shows the life of four sisters whose average age is 90 years old. All of them live in good health and love to chit-chat. The eldest daughter (96) and second daughter (92) have lost their husbands and live by themselves. The third daughter (89) is physically strong and goes out to the supermarket by bicycle. The fourth daughter (86) still drives a car.
