An old man about to die gives all his fortune to a young beggar he meets in an Arabian town. He takes him to his house (now the poor man's property) and he strongly advises him not to open one of the doors, the seventh door. "I could throw the key into the sea" says the young lad" No use, you'd dive to get it back". The young man is curious and he cannot resist temptation: he opens the forbidden door. A strange world is waiting for him where a girl, Leila, will be his guide .
