Eight years after the third film, the OSS has become the world's top spy agency, while the Spy Kids department has since become defunct. Retired spy Marissa is called back into action, and to bond with her new stepchildren Rebecca and Cecil, she invites them along to stop the evil Timekeeper from taking over the world.
