Four women, each carrying their own unique burdens, set off on a journey together. As they travel, they reflect on their pasts and seek to begin anew. Jinko (played by Aoi Miyazaki) and Motoko (portrayed by Sakura Ando) have been close since their college years. They hear a startling rumor about their old friend and former classmate, Miki (Kazue Fukiishi), who reportedly ventured into the sea but emerged unharmed. Concerned, Jinko and Motoko decide to check on Miki’s well-being. Joining them is Haraki (Shiori Kutsuna), whom Jinko met at her library job, and who offers to drive. Thus begins their brief road trip, spanning one night and two days.
