60-year-old Sawako Matsui. A housewife married for 35 years, living with her executive husband. Her eldest daughter, Junko, lives in Tokyo, and she has two grandchildren. Even after her only daughter's marriage, family bonds remain strong. Her intimate life with her husband has long been absent, and though she felt loneliness, she quietly accepted it as unavoidable. But this year, getting a smartphone opened her to new online information, exposing her to sexual worlds she'd never known before. Seeing women her age engaging in affairs or seeking new pleasures surprised her—and awakened her own desires. One day, she says, "I'm sorry to trouble you after such a long time, but please take care of me today," announcing a bold new step. This is the documentary of a mature wife in her sixties—chaste and devoted—taking her first step into a new chapter. Watch closely as her heart transforms and new possibilities unfold in her life.
