At just three months of age, he had seen more than anyone should ever have to see. He was the offspring of two champions in the bloody, sadistic world of dog-fighting. An American Staffordshire Bull Terrier, the pup was bred to be a killer, trained in violence and fear by the brutal Leroy "Big-Un" Keller. One night it becomes too much, and the young dog runs away. The pup escapes into the arms of another survivor, Rick Simpson, the man who finally gives him a name: Billy Bob. With Rick, Billy's world opens up to friendship and love. Billy is able to connect with those in need of comfort and help people in trouble. However, Billy is pursued by the savage Keller clan as well as animal control forces who cannot look beyond the stereotypes of Billy's breed to see the loving, loyal animal underneath. The bond between Rick and Billy runs strong and true, but will it be enough to put an end to Keller's vicious cycle of abuse so Billy can live free?
