Pei Gang, the only heir of his generation, is spoiled by his grandmother since birth, and grows up to be a brute and bully. One day, on impulse, he commits three cruel murders during a brawl and is sentenced to death row. While he unrepentantly stays in prison awaiting execution next autumn, his grandmother goes to great lengths to free him, manipulating inside and outside the court, including bribery and exerting pressure on related agents. When all her efforts fail, she turns to Lian, a distant relative she has raised since childhood, and asks her to spend a night in the cell with Pei Gang to bear his child. Affected by Lian’s self-sacrifice to keep his family line, his grandmother’s death, and the correctional education he receives in prison, Pei Gang is spiritually transformed into a new man. He carries this new identity with him to his execution in autumn.
