Agents Gregorio (Antonio Banderas) and Ingrid (Carla Gugino) are the world's top agents. They met during a mission and fell in love. From then on, the world lost two outstanding agents and gained a happy family. Nine years have passed in a flash, and the peaceful world is in turmoil again. Gregorio's former comrades-in-arms disappeared one after another mysteriously. This must be the conspiracy again. In desperation, Gregorio and Ingrid had to go out again, but they were also kidnapped! Now, the burden can only fall on Carmen (Alexa Vega) and Juni (Daryl Sabara), two little kids who grew up in the agent's house. Our agent prodigy is going to the battle.
