Jiang Chen saw Lu Chengfeng for the first time and thought that this man was really handsome, but unfortunately he was too cold. As a third-year graduate student in criminal psychology, she was sent to the Linzhou City Public Security Bureau's Criminal Investigation Detachment for an internship. The police officer she coached happened to be the deputy detachment leader who was known for his "little talk, cold face, and ruthless crime solving". On the first day, Lu Chengfeng threw her three old case files: A woman living alone disappeared, and a handwritten note was left at the scene - "I'm sorry, I need your help."
It hasn't been broken in three years. Three families are waiting for an answer.
Jiang Chen spent three days drawing a psychological portrait of the murderer from his handwriting, wording, and folding methods: a 25-30-year-old male, living alone, with social barriers, and an extraordinary obsession with "forgiveness." Lu Chengfeng didn't praise her, and only said two words: "Continue." Until the fourth disappearance occurred. The note at the scene read "I'm sorry, I need you to help me" - the wording changed. The killer evolves. Jiang Chen began to follow him to the scene, stay in place, and observe the interrogation. She found that this man looked like a silent mountain on the surface, but she remembered that she drank soy milk with less sugar, forgot to eat when reading files, and must be nervous when drawing circles. He never said unnecessary words, but every sentence was on point.
What she didn't know was that when Lu Chengfeng saw her notes for the first time, he knew that this intern would change his life.
This is a story about abyss and looking back. She drew a portrait on paper, and he chased the murderer in the dark abyss. The most touching sentence he ever said was - "I won't live even if you die."
