Synopsis A depressed former champion awakes. He's tired, a bit out of shape, and he's suffering from a guilty conscience. His career in the ring ended abruptly when he killed his rival with a single punch. That's why Marcos Wainsberg, the Inca of the Sinai, wants to quit fighting. But today is not the day to be thinking about that. Today his ex-girlfriend will come in peace and his luck seems to be taking a turn for the better. That is, until the doorbell rings and he opens it to find his cousin, Huguito, the black sheep of the family and someone who always brings trouble. Today can be one of those days when everything changes. But will the change last forever? Regurgitated from the very insides of genre cinema, Diablo's furious and corrosive progression leaves you breathless, but also provokes a remarkable morbid pleasure with its violence, black humor, and hardcore swagger.
