El Marginal takes place inside a prison where the real power is not held by the laws but by the prisoners and the corrupt who manage them from the outside.

His brother Diosito is unpredictable, violent and manipulative, and embodies the constant chaos of the place, Colombia or James the helper of house one, Barney as the security of the Borges.
