Cassius X puts a period of often-overlooked history into the spotlight – the period when Cassius Clay fought his way to achieving his lifelong dream of becoming World Heavyweight Champion while embarking on a secret spiritual journey.
The story takes place in alternative America where the blacks are members of social elite, and whites are inhabitants of inner city ghettos. Louis Pinnock is a white worker in a chocolate factory, loving husband and father of two children. While delivering a package for black CEO Thaddeus Thomas, he is mistaken for a voyeur and, as a result, loses his job, gets beaten by black cops and his family gets evicted from their home. Desperate Pinnock takes a gun and kidnaps Thomas, demanding justice.
