Ben and Hero, the incredible search-and-rescue dog, have saved the day before - but never like this. Ben's town is in trouble when two convicts escape from a nearby prison. His dad, a police officer, sets off to find the men and bring them to justice, but then Ben's dad disappears and the trail goes cold. Ben knows that it's up to him and Hero to solve the case. As they embark on their most dangerous mission yet, the two best friends must stock up on their courage in order to outwit the fugitives and bring Ben's dad home. Are the two heroes up to the challenge?
