The naturalist and ethologist Jorge Alesanco has lived with the great kings of the Masai Mara for more than 15 years, following them, loving them and discovering unusual behaviors which have never before been documented until now.
Jorge Alesanco is the first man that was accepted by a pride of wild lions. But getting to know the great lion kings of the Savannah has been the work of years, full of difficult moments.
Anayeruca, the lioness who was the first to accept Jorge Alesanco as part of the pride, is exposed to grave danger. After the kingdom was conquered by nomadic lions, she has been forced to flee with her two cubs.
Scipio, the great lion king who accepted Jorge Alesanco into the pride, forms a coalition to take back his kingdom. In the days of the battle, Jorge recalls the 3,000 nights he has spent with lions, which led him to be accepted by the pride.
