This work is set in the beautiful scenery of Japan and tells the story of a husband driving his wife's car to pursue a spiritual journey. Hasumi Kikuo (Kenichi Takito), who lost his wife Minako (Machiko Ono) in an accident, learned that her car "Grace" only had a record of places far away from her daily life. Kikuo suspected that his wife was unfaithful and embarked on a journey to solve the mystery. Every place he went to would dig into his dusty past and touch Minako's thoughts.
