A navigator gets audience with Isabel. He wants Castilla to finance a trip that would open a new route to the Indies. It's Christopher Columbus. The queen is attracted to the idea, but in the middle of a war against the infidel it is difficult to gather the necessary means.The kings take advantage of the capture of Boabdil to launch him against the side of his father, now captained by El Zagal. Aixa and her son, however, have their own plans: they try to buy time to gather support. In the future, having got rid of their rivals in Granada, they will stop the Christians' feet.
