When a mysterious nomad girl is offered up as an item of trade, she seeks refuge by forming a tenacious friendship with the local cave-painter-turned-outcast. Together they set out on a dangerous mission to bring truth to their corrupt tribe with the help of their new discovery (via some psychotropic mushrooms) - drawings that tell a story. Subsequently, they become enmeshed in the violent power struggles and sensual intrigues between the alpha males and alpha females.
