Housewife Rina (30) embarks on a two-day, one-night trip with a man and a woman she’s meeting for the first time. For twenty-four hours, we closely capture her life as she escapes reality and surrenders herself to a secret affair. Two years into their relationship, they married through a workplace connection, and now a year has nearly passed. Tired of a married life so different from what she once imagined, Rina has been sacrificing herself for her husband’s dream of owning a home. With household food expenses strictly limited to 20,000 yen per month—any amount over causing her husband to fly into a rage—Rina’s heart slowly approaches its breaking point.
