14岁的莉莉丝的生活与一个正常的青少年相似，但也有一个特点：她是魔鬼的女儿，和他一起生活在地狱里。因为她在那里完全无聊，想玩得开心，想探索世界，所以她和父亲订了一个协议：允许她去地球一个星期，但她必须把好人变成坏人。如果她在这一挑战中取得成功，她可能会永远留在地球上；否则她将陷入地狱般枯燥的工作，簿记在黑社会。
　　The life of 14-year-old Lilith is similar to that of a normal teenager, but there is a peculiarity: she is the daughter of the devil and lives with him in hell. Because she is totally bored there and wants to have fun and explore the world, she makes a pact with her father: she will be allowed to go to earth for a week – but she has to convert a good person to evil there. If she succeeds in this challenge, she may stay on earth forever; otherwise she will be stuck in a hell of a boring job bookkeeping in the underworld.
