"The Underworld" is a project inspired a book called "The Rogue Lawyer" by John Grisham.
It represents the life phases of people who see crime as the only option to survive.
On the first picture we see the entrance to this world, which for the common people it may seem like hell.
On the second one it's the police coming towards you while you try to catch the dirty and dangerous money. It's also very common to belive that god is always looking out for you when times get darker and darker, but is he?
The third one is the end of the line, the real hell in earth: The prison.
