Gu Huaiyuan, a 32-year-old elite lawyer, lives a rigorous and precise life, like a precision instrument that never makes mistakes, but in fact, he uses absolute rationality to imprison an unbearable past. Lin Jingluo, a 26-year-old freelance photographer, seems free and uninhibited, capturing the warmth of the world with his lens, but he is burdened with childhood trauma that cannot be healed. They met in a bizarre inheritance dispute case. Gu Huaiyuan was the defendant's attorney, and Lin Jingluo was the key witness in the case. From the initial misunderstanding and opposition, to being forced to uncover each other's scars in the process of searching for the truth, they are like two solitary whales meeting in the deep sea. Through the frequencies emitted by each other, they gradually heal the ravines in their hearts, face the huge waves from family, society and the past together, and finally complete each other's redemption and find their true selves.
