When the world is in trouble they call in their top secret agents: Carmen (Alexa Vega) and Juni (Daryl Sabara) Cortez. Their newest mission takes them to a mysterious island where they meet a wildly inventive genetic scientist (Steve Buscemi) and his imaginative creatures, while fighting the forces of rival SPY kids, Gary (Matt O'Leary) and Gerti (Emily Osment) Giggles, as they head right into a trap that will test each and every Cortez spy, from super spies Mom and Dad to their SPY grandparents (Ricardo Montalban, Holland Taylor). This summer Carmen and Juni go on a mission so big, theyÂ’ll have to bring the whole family.
