When a homeless amputee who lost the right side of his head and body is chased by a crippled criminal who appears to be his missing half, he must overwhelm him to discover the origin of their condition and become a full man.
Not sure how this will look, two halves of the same man hopping after each other on one leg each?
Can you elaborate on the basic logic of the world the premise is in?
Also what is the plot what does the homeless person want? Is it to become whole again or is there something else?
