Best friends Callum and Sephy live in a racist society where white skinned people (noughts) are ruled by black skinned people (crosses). Sephy is black, and daughter of one of the most influential men in the country, Mr. Hadley. Callum is white and has been admitted to Sephy's school, which has started enrolling the brightest noughts.
What type of struggles does Callum go through in everyday life? Will Callum and Sephy ever be allowed to be friends? And will Callum ever stand up for what he believes in?
