The Enterprise encounters the SS Botany Bay. She has been in space for centuries, carrying seventy two men and women in suspended animation. Kirk and Spock realize these people are dangerous refugees from Earth's last great war. The result of selective breeding and genetic engineering, these men and women possess superior power and skill... and superior ambition that drives their plans for the modern era. They awaken the group's leader, Khan Noonien Singh, but he quickly takes over the Enterprise and plans to lead a new war of conquest in the 23rd century.
