像往常一样，走在下班路上的和子（尾野真千子饰演）上了天桥，发现前面有个拄着双拐走路的女孩环（佐伯日菜子饰演）。和子很快留意到这个陌生神秘女子，在她左脚上打着白色厚重石膏，看着既不灵活又不方便。果然在和子表示想帮助对方时，环用一种不太自然、没有敬语的命令口吻——要和子把她右脚的高跟鞋脱掉，说是穿着不适。

22-year old secretary Kazuko first bumps into Tamaki on the way back from work. Tamaki is crawling along the sidewalk on crutches at a snail's pace, and stumbles into the young audiotypist after apparently having trouble with an ill-fitting shoe over her cast. After helping her back to her feet, Kazuko follows Tamaki back to her apartment, the two of them barely exchanging words. Once in Tamaki's room, Kazuko is dispatched on an errand to fetch some beer... Their game begins..

Kazuko conhece uma mulher chamada Tamaki, que está aparentemente tendo dificuldades para andar com sua perna engessada. Ela a ajuda a voltar para seu apartamento e como as duas, a partir desse momento, começam a passar mais tempo juntas, Kazuko que até então seguia sua previsível rotina gradualmente se vê envolvida na estranha vida de Tamaki.
