On Guixu Island, which is isolated from the world, Lin Zhou is the only "memory ferryman". Day after day, he carries the light dust of memories sent by people, carrying pain or sweetness, to the sea of forgetfulness that can swallow everything. He firmly believed that forgetting was the ultimate mercy, until a mysterious woman named "tide" landed on the island. She doesn't want to forget, she just wants to find a memory that was stripped away by her loved ones. Her pursuit, like a pebble thrown into stagnant water, not only disturbed Lin Zhou's peace, but also began to awaken his past that was buried deep in his heart and had long been banished by himself. On this island of memory, the encounter of two souls is destined to set off a stormy sea against forgetfulness.
