What will happen when the most envied gang of Seoul is obliged to take care of an unknown girl who doesn’t even know her own name?

The Black Pearl 476 is a gang composed of three boys and two girls who only think about one thing: Money. They all grew up in an orphanage despising life, challenging all symbols of authority, swearing that one day they would be able to escape from the dark, but their past can’t be erased. What if they find the light, a light that no one has ever expected? Will they be able to move on in order to find another aim except money? Will they live in peace for their rest of their lives forgetting that they’re outcasts? Will that light bring them to heaven or to hell?
