Shen Du, a 28-year-old psychological counselor, specializes in post-traumatic stress disorder.
She is calm, controlled and professional, and her colleagues think she
"Like a cup of warm water, neither hot nor cold."
No one knows that at the age of twelve, she was the only survivor of the serial killer "The Ferryman". He was rescued after being imprisoned for forty-seven days. He grew up in an orphanage and received a scholarship to study for a doctorate in psychology.
She has a secret - she can "smell" fear. This is the survival instinct she was forced to train during her captivity, which she calls "the gift of the abyss." She never told anyone.
Twelve years later, she thought she had escaped.
Until a visitor's dream description completely matched the details of her imprisonment. At the same time, criminal police captain Lu Zheng brought news: there was a suspected "ferryman" imitation case.
The killer was never caught. Maybe even... Maybe never stopped.
Shen Du was forced to face the past and began to assist the police in criminal psychological profiling. She discovered that the imitator knew some details that "shouldn't be known" - these details have never been made public, which means that the imitator had contact with the real "Ferryman".
And the people around her—the tutor Fang Zhidu, the assistant Su Mian, and the visitor Lin Xu—all seem to be hiding secrets.
The abyss never let her go.
But this time, she didn't run away.
She wanted to end this symbol with her own hands.
Intention: The real salvation is not to forget the abyss, but to continue walking with the scars
