Mew is a kitten, part of a family that has to hide and scrounge to survive. They are being hunted by the Death Dogs, an elite pack of genetically enhanced kanines with a taste for blood and revenge. When the dogs come for the family, they chase Mew's brother, Fluff, into a river. Mew follows him, only to find him dying. His last words were "Avenge me." Now Mew is out for revenge. Between supernatural speed powers her father's ghost gives her and a clan of cats, gathered by Mew to take down the enemies, the Death Dogs are in for a fight with this angry rogue.
