Scared of life and lacking the courage to be himself, Ludovico lives hidden away in his grandmother's old apartment. One night, the wickedness of the world goes to visit him in the form of Jack, a boy who is Ludovico's age but has the opposite character hard, determined, perhaps criminal. The forced cohabitation of two human beings who couldn't seem more different from one another turns into an initiation rite to adulthood, the discovery of their true and respective personalities. And when the harsh reality that is mercilessly stalking them appears to present the bill, they will have to face it, bolstered by a new awareness and unhoped-for courage.倒是黑无常一语道破了真相：“鬼都是人变成的，人什么样子你没见过？鬼只有比人更坏，哪有比人更好的道理？地府公正严明？嘿嘿……哪个告诉你的？”
