The tribe has been alone on the farm for many seasons, struggling to survive by their wits and will, unaided by the humans who abandoned them there years ago. Few members of the tribe outside of Tia, the eldest, and her fiercely loyal companion Bella, remember a time when two-legs--the cats' name for humans--lived in the farmhouse. Suddenly, the tribe's territory is invaded by a young two-legs couple, and the frightened cats ask themselves why have two-legs come to live there after so many seasons and what will happen to the tribe at the hands of these often cruel creatures?
