Duma is a cheetah who lives peacefully with her wolf pack in a world galaxies away from planet Earth, called “the Oasis”. They are different from ordinary animals; they are tribal and anthromorphic warriors who train themselves and each other to defend Earth from creatures dubbed the “Outsiders”. These monsters have suddenly increased their attacks, and the animals from the Oasis have traveled through dimensions between their world and ours to stop them. One by one, they die or disappear... and it’s up to Duma, her best friend, Thorn, and a very unlikely trio of boys to stop them.
