After her husband's death, Reiko lives with her son and his wife. While she's happy to share a home with her son and his kind spouse, she feels a quiet sadness watching their close, loving relationship. One day, she finds a flyer in the mailbox advertising a "parts modeling audition." Intrigued by the simple job—wearing a leotard and having photos taken with a mobile phone for review—she asks her son to help her with the shoot. As the sessions continue, new feelings begin to stir within her toward her son, and their relationship starts to change.
