Shin-ichi operates a small noodle-making factory with his wife Hanako.
Their divorced daughter Kotoe and granddaughter Sachi have both come back to live with them.
Hanako notices something strange about Kotoe, and realizes she’s pregnant. Kotoe announces she’s getting married a second time. Shin-ichi is very angry at first, but eventually gives his blessing.

Shin-ichi, who’s been struggling to sleep, is invited to a sutra reading at a temple owned by his childhood friend-turned priest, Minoru. But that night Shin-ichi is killed in an accident, and Hanako suddenly finds herself alone.
One day Shin-ichi’s cell phone, which he left in his office, begins to ring. An unfamiliar woman’s name ‘Hitomi’ shows up on the display. Hanako is determined to discover the truth behind the call.
