In the twenty-sixth year of the Republic of China, war spread across the rivers and rivers, and corruption and conspiracy grew in the rainy alleys of the foggy city.
Mo Nian was once the most elegant and mysterious socialite in Shanghai. After the news came that her husband Lin Wang had "died in battle", she became a lonely figure wandering in the cemetery. Day after day, her longing gnawed at her bones and burned her heart, and she finally transformed into the legendary "Nian" - a white bird with a red mole on its belly and blood-red eyes, hovering over her deceased husband's tomb, using its sharp claws to tear apart all the malicious intent that came near.
No one knew that Lin Wang's soul was sealed in the dolphin whistle coveted by the warlord. In order to protect his wife Zhou Quan, he faked his death and escaped. However, after learning that Mo Nian had transformed into Nian, he exchanged half his soul for the Taoist secret method and became the ghost fish "Forget" in the River Styx. He is the messenger of extradition from reincarnation, but he wants to take his wife to the afterlife with his own hands; she is a bird with obsession that turns into a demon, but she wants to fight against fate to the end in the bloody dusk.
When the rain curtain falls, the whistle of dolphins cuts through the river surface, and the fish of the Styx and the chanting bird meet in the fog. Is it to awaken the fallen love, or to obey the fate of reincarnation?
In a troubled world where corruption is rampant, a fate woven by longing and lies has just begun.
