Amores Perros (2000)

The lives of three strangers from different segments of society intertwine after a tragic car crash in Mexico city: a young man who enters the feral world of dogfighting to make money in order to run away with his brother’s wife. A supermodel whose life has been derailed by the crash and is struggling to find her dog that has disappeared into her apartment floorboard. And an aging hitman who lives with a pack of stray dogs and is desperate to reconnect with his estranged daughter.
