Tomoyo Shiino, an office worker, receives news that her friend Mariko Ikagawa has died by suicide. Having met Mariko recently without noticing any signs of distress, Tomoyo is consumed by guilt over her inability to recognize Mariko's suffering. Determined to do something for her late friend, Tomoyo resolves to steal Mariko's ashes, believing that Mariko's abusive father—who subjected her to psychological and sexual violence—would not give her a proper memorial.
Armed with a knife, Tomoyo breaks into the Ikagawa household and seizes the ashes, intending to scatter them at Marigaoaka Cape, a place Mariko had once expressed a desire to visit. However, during her journey, she is robbed of all her belongings except the ashes. Soon after, a mysterious young man named Makio appears, offering her money and assistance. Though suspicious of his intentions, Tomoyo accepts his help and eventually reaches Marigaoaka Cape.
Upon arrival, overwhelmed by grief and guilt, Tomoyo impulsively attempts to jump off a cliff. However, at the last moment, she spots a girl who bears an uncanny resemblance to Mariko being pursued by a stalker. Acting on instinct, Tomoyo rushes to intervene, setting in motion a series of events that force her to confront her own despair and the unresolved pain of Mariko's death.
