On "Forget the River Island", people can pay to delete painful memories and become "complete" happy people. Lin Feng is the best memory keeper on the island. He has sealed up the past they abandoned for countless clients, but he has a blank memory - five years ago, he erased all his memories with the highest authority. One day, a memory fragment that was supposed to be completely destroyed accidentally flowed into his system. The desperate cry of a strange woman in the fragment aroused inexplicable pain in his heart. In order to pursue the truth, Lin Feng embarked on a forbidden road to retrieve his past, only to discover that this forgotten island itself was built on a huge conspiracy built of lies.
