On the night of the car accident, Qi Yan's legs were completely destroyed. When he woke up, he saw his brother Qi Xiao smearing blood on the steering wheel. Three years later, his body was reborn. He disguised himself as a docile patient and secretly investigated the truth. Psychotherapist Lin Wan's keenness, lawyer Zhou Yanzhi's lies, and witness Shen Zhao's silence revealed the family's shady story layer by layer. Qi Xiao, on the other hand, plays the piano during the day and sends anonymous blood letters to his enemies at night - he wants to save his brother, but he is afraid that he will be swallowed up first. The blood has not dried yet, the lies have just sprouted, and the real storm has just begun.
