In Peter’s family the mother dies, and all of a sudden he has to take care of everyone: his little brother, nicknamed Cabrera; his sister Valéria, who suffers from unrequited love; his father, who had all but the middle finger of his right hand bitten off by a dog when he was a child; and a messy Grandma, who decided to move in after their mother’s death. To make matters worse, the father lives in a pit. It’s no ordinary pit, but a pit in a couch, where the father spends his days blowing up tanks in a computer game with his middle finger. Consequently, the children call him Tankman. As a way to distract themselves from how much they miss their mother, they adopt a hyperactive little dog. Unfortunately, Peter gets stuck taking it for walks all the time, because no one else feels like it. Peter is twenty-five and takes everything seriously. Perhaps too seriously.
