The storm tore the sky apart, and isolated islands emerged from the black tide. Haiyao, a young woman who makes a living by listening to the whispers of the waves, was thrown here by fate. Her companions have disappeared in the storm, leaving her alone with the echoes deep in the island. There is no light on the island, and eternal secrets are buried under the moist moss. There are strange footsteps wandering in the forest every night. Haiyao longs to escape, but gradually loses herself in the strange call of the island - she discovers that only by unraveling the strange connection between the island and her own memory can she survive. The core conflict is that Haiyao must identify the boundary between reality and illusion in fear and loneliness, and choose to uncover the truth or completely become part of the island. The story revolves around Hai Yao's psychological fission, blends tidal imagery and folk ghost songs, and weaves an island elegy about self-salvation and dark temptation.
