When his mother-in-law is struck by a terminal illness requiring an enormous sum for surgery, the husband finds himself unable to cover the costs on his salary alone. Forced to take out loans from a finance company, he becomes increasingly desperate and takes out his frustration on his wife, Ai. Amid his despair and isolation, one person stands by her—Sonanaka, the manager who once oversaw Ai during her days as a popular beer company campaign girl. To protect the family she holds most dear, Ai resolves to put on a leotard once again and walk a new path. This decision carries the weight of her inner conflict between past and present, as well as the depth of her love.
