On the isolated "Island of Silence", memory is a luxury that will be slowly stripped away. Lin Ci is the "memory keeper" here, and his job is to back up the last precious memories for the residents who are about to forget everything. Armed with professionalism and alienation, he calmly watches over the countless dusty past. Until the arrival of the painter Su Wan, she refused to be "cured" and used her paintbrush to fight against forgetfulness. Her persistence was like a stone thrown into stagnant water. It not only caused ripples in Lin Ci's heart, but also made him wonder whether there was a cruel truth about memory and human nature hidden under the seemingly benign appearance of this isolated island.
