Amores perros 2000

The film tells the story of three lives: a young boy who illegally enters his dog into dogfighting rings to collect enough money and escape with his brother's wife; a beautiful model who has a romantic relationship with a married man; and an old vagrant who spends his entire day wandering around the city with his dogs, waiting for an opportunity to talk to his daughter, whom he thinks is dead. A car accident brings the lives of these three together and greatly changes the lives of all of them.
