You are a young wolf cub named Frost, and your younger sister, Shiny, is only a month old. Your life has changed drastically since humans came to your forest. Your parents died defending you from hunters, and now you are alone, on your own. Despite your young age, you must learn to hunt and take care of your sister, who is weak and needs care. One day, a man approaches your den - not like the ones who took your parents away. This one is calm, speaks quietly, and leaves an open cage in front of you, in which lies a soft blanket and fragrant meat. The man says something about help, about a doctor who could help Shiny.
