São Paulo, 2007. Santana works as a dogcatcher, picking up stray animals. He is a friendly guy, averse to trouble, who has always kept violence away from the doorsteps of his home. One day, he catches a very big dog in a school. Some days later, comes the animal’s owner: Babyface, a sociopath ex-cop. The man is furious, considering his dog to be “kidnapped”, and demands immediate restitution of his pet. But the dog is not coming back: according to the law, the animal was put to sleep. In a misunderstanding, Babyface argue with Santana, blaming him for his pet’s death. From this moment on, Santana’s life will be completely changed.
