"Genghis Khan” tells the story of Temujin (Manuel Conde), a young Mongol prince who takes part in a series of challenges against rival tribes for land rights. Under the auspices of Burchou (Lou Salvador) and his beautiful daughter, Lei Hai (Elvira Reyes), Temujin uses his wits to prevail against larger, stronger opponents to emerge victorious. Unknown to any of the participants, Burchou’s advisor had arranged for his lord’s forces to massacre all the rival tribal leaders at that evening’s celebratory feast. Temujin barely escapes with his life, and makes his way home to find his village destroyed and his mother near death. Instilled with a desire for revenge, the young prince begins spreading the word of Burchou’s treachery, competing at the Man of Men contest, falling in love with the enemy commander's daughter, and struggling to restore his demolished hometown, forging alliances and building a power base that will culminate with him ascending to the position of great conqueror.
