This is a hardboiled story of a koala, the last of his kind. He serves as an independent detective shlepping around the under, surviving off any of those who can pay his price. It's a post-apocalyptic time and many resources are gone and used up by an ever-increasing population. Only those in the upper control what is left. This means crime and murder are at an all-time high. Jax will find that there is even some things he can't solve.
