Life swings between triumph and failure in the enthralling “El Gran Salto” produced by Atresmedia TV in collaboration with Banijay’s Diagonal TV, the force behind shows such as “Isabel” and “La Catedral del Mar.”

Spanish star Óscar Casas stars as Olympic Gold Medalist gymnast Gervasio Deferr. The series is written by “Bye” scribe José Rodríguez and based on the Olympian’s own book of his struggles.

“Success is like a pendulum; it goes back and forth and is very delicate because if you don’t control it, it can screw up your life,” Deferr’s coach advises in the series opener.
