In the fantastic series "Noughts + Crosses," viewers find themselves in one of the parallel universes where history took a different path. Over 700 years ago, the state of Aprica waged war on Europe and conquered all countries, including the island of Britain. Now, people of color rule the world. They are the prominent political figures, lawmakers, scientists, and writers. The white race has been oppressed for centuries, but resistance begins in Albion. It is during this time that a dark-skinned girl named Sephy and a white boy named Callum fall in love with each other.
