Carlos Vallecillo is a single father, normally a hardworking, cheerful, and jovial man, an immigrant wanting to make the best life for his kid. He was recently bitten by a strange dog. He's acting strange, more sensitive to sound and smell, angrier, being overprotective and almost territorial over his child, constantly hungry, having intrusive thoughts, and being restless. Unbeknownst to him he is turning into a rabid werewolf. His wolf side views his child as his 'pup'.
