Plot: Juni (Sabara) has retired from the OSS. He’s doing small jobs now for local kids to save up money to buy the latest game craze: Game Over, created by the mysterious Toymaker (Stallone). He’s forced back into the OSS when he finds out his sister Carmen (Vega) has become trapped in the game. Now Juni, with a little help from Grandpa (Montalban), must venture into the game, save his sister and stop the Toymaker.

Plot: Carmen (Vega) and Juni (Sabara) are back. Things aren’t going well for them. They’ve got new Spy Kid agents Gary (O’Leary) and Gerdi Giggles (Osment) competing with them. When a new device, the Transmooker, is stolen from the president by mysterious henchmen, Juni is blamed and gets fired. Gary and Gerdi are given the assignment to get it back. But, Carmen and Juni need to get it back so they can clear Juni’s name. Little do they know that when they disappear, their parents (and grandparents) are hot on their trail. Now the family must get the Transmooker device back, clear Juni’s name…and do it before Gary and Gerdi do.
