Emergency doctor Feng Xuyang received a mysterious phone call one day, claiming that his wife Lin Wanqing was about to be killed. He hurried to the abandoned warehouse on the outskirts of the city, but only found a blood-stained wedding ring.
Three years ago, he rescued Lin Wanqing who lost her memory in a heavy rain. After a drunken misunderstanding, the two got married. Life seems peaceful and warm until this ring breaks everything.
The bruises on her wrists, the twinkling eyes, the theft from the pharmacy late at night... The wife seems to be hiding a shocking secret.
At the same time, the old love Su Nian, who "died by falling into the sea" five years ago, suddenly reappeared, leaving a warning: "Don't trust Lin Wanqing."
Feng Xuyang discovered that he had a mysterious antibody hidden in his body, and became the target of competition between the two dark organizations "Night Owl" and "Justice League".
The old love is still alive, the new wife is an undercover agent, the truth about his father's disappearance, the conspiracy behind the antibodies, and a mystery of grudges spanning five years are drawing him into an inescapable whirlpool...
