Marisa, after waking up to a call from her mother, finds herself immersed in introspection amidst mysterious events. She is startled by a strange sound of the sea, something unusual since moving to her husband’s city.

When Marisa investigates the source of the sound, she discovers that her bedroom door mysteriously leads to a beach in her hometown. Involuntarily drawn to the ocean, she walks until she drowns in a complex of agony. At least, until awakening comes.
