Married woman Masami (38) has been remarried for five years. She continues to live as a family of four with her two children from her previous marriage. She once believed her whirlwind marriage would bring lasting happiness, but was driven to divorce by her husband's infidelity and harassment from unknown women. Afterward, she raised her children in a cheap apartment, working day and night to survive. It was only because of her children that she found the strength to keep going, and with that resolve, she began a new married life. While her current family relationships are stable, deep down she longs to reclaim her identity as a woman and rediscover her lost radiance—setting out on a new journey. On a two-day, one-night trip with a complete stranger, this conflicted housewife spends 24 hours in close quarters, surrendering to a night of forbidden passion. This is the beginning of a new emotion she has truly desired.
