On the surface, Marissa Cortez Wilson (Jessica Alba) has it all…married to a famous spy hunting television reporter, a new baby and intelligent twin step kids. But in reality, trying to mother Rebecca (Rowan Blanchard) and Cecil (Mason Cook), who clearly don’t want her around, is her toughest challenge yet. Marissa’s world is turned upside down when the maniacal Timekeeper (Jeremy Piven) threatens to take over the planet and she’s called back into action. Rebecca and Cecil are then forced to put their bickering aside and rely on their wits. With a little help from a couple of very familiar Spy Kids, Carmen (Alexa Vega) and Juni Cortez (Daryl Sabara), and some mind-blowing gadgets, they just may be able to save the world and possibly bring their family together while they’re at it.
