Tui is shocked to one day find her good friend Kiwi has been killed by a stoat. She sets out to find a way to kill the stoat, not immediately realising her mission will turn out to encompass all the predators in her home forest. Relaying her dismay to a young boy living on a farm adjoining her home, the boy takes her wish further, not only killing the stoat, but also setting traps and poisons to kill the other predators in the bush.
