14歲的莉莉絲的生活與一個正常的青少年相似，但也有一個特點：她是魔鬼的女兒，和他一起生活在地獄裏。因爲她在那裏完全無聊，想玩得開心，想探索世界，所以她和父親訂了一個協議：允許她去地球一個星期，但她必須把好人變成壞人。如果她在這一挑戰中取得成功，她可能會永遠留在地球上；否則她將陷入地獄般枯燥的工作，簿記在黑社會。
　　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.
