However, despite the outward semblance of domestic bliss, Mary feels trapped and unfulfilled in her life as a housewife. As she reflects on her life choices, including a romance during college and a stint as a flight attendant, she grows increasingly disillusioned.

Her quest for personal fulfillment is fraught with challenges and difficult decisions, forcing her to confront her past and the choices that led her to her current state.
