神马四兄弟Colombian music icon Juanes plays Moisés, the eldest of three brothers plying this perilous trade and the linchpin of the operation, while Alberto Guerra delivers a compelling performance as Ulises, a man paralyzed by conflicting decisions and haunted by fear and grief. When Juan (Alejandro Speitzer) — the youngest of the brothers — is coerced into working for a more powerful, rival criminal organization, the shocking underbelly of the business is laid bare and there are tragic consequences.
