Renzo is a quiet kid, content to let his charismatic friend Paloma do all the talking while he dreams of playing the guitar and surfing out in California, becoming a veterinarian, and maybe learning more about the war hero father he's never known. He lives on a farm with his mom, grandfather, and an extraordinary pig named Marty ... a pig who thinks he's a dog, that is. Renzo and Marty s friendship is one-of-a-kind, but the bigger Marty gets, the harder it is for Renzo to justify his unusual pet to his penny-pinching mom. So when she threatens to sell Marty or worse Renzo decides it s up to him and Paloma to save Marty once and for all.
