Shimizu Yuichi (Tsumabuki Satoshi) is a shy and lonely day laborer looking for love. He aimlessly spends time corresponding with girls via telephone dating services and going on random encounters with girls looking for spending cash. His world is shattered one day when he is involved in the murder of one of his former encounters, the sweet-faced Ishibashi Yoshino (Mitsushima Hikari) who, after being jilted by playboy Masuo Keijo (Okada Masaki), berates and mocks the troubled loner.
