When Yaz and her dog Hercules find a dead man on a bench along the canal with chicken bones lying around him, she immediately calls Louise – and the police.

The case is odd: a chicken bone has been forcibly rammed down the victim’s throat, and the last person to see him was their friend – and Pack-mate – Claire. When the police take Claire into custody, the Pack mobilise, determined to find the real killer. The trail leads them to the new Cluckin’ Good Chicken shop, who not only have a gang that loiter outside, smoking weed and harassing passers-by, but have also managed to create issues with the locals.

As the Pack's investigation into the chicken shop progresses, establishing links with organised crime that might possibly connect to the local council, Louise and her friends find themselves in mortal danger. Can the Pack sniff out the killer and get to the bones of the mystery?
