Budding teen spy Connor Heath's dreams of adventure come true when a mysterious foreign girl named Gisela moves in with his family. But when it becomes clear that will do everything in her power to return home, Connor finds himself using all of his spy skills to get her to stay. Good thing too because it looks like Gisela is at the center of a major conspiracy and in more danger than he or she could ever imagine.

Gisela and Connor clash: She tries to prove she's unsafe with the Heath family so she can get sent home; he tries to prove his spy skills are the key to her protection so she can stay. But Connor’s push to convince Gisela to stay comes up short when she “fires” him as her guide and “hires” his bumbling best friend, Whynot. Things get even worse when Connor accidentally takes down Gisela’s bodyguard in a case of mistaken identity. Meanwhile, Ty intercepts a mysterious package in the mail… a package that’s full of money.

It’s the first day of school and Gisela pulls out all the stops in her mission to get sent back home to Cordobá. Her goal: get expelled. But her attitude takes a 180 when her new bodyguard – Zatari – comes to town. Thing is, Connor doesn’t think Zatari is who she says she is and will do anything – even blow off his major crush, Tanya – to find out what she’s hiding.

Connor’s excitement over the arrival of new secret service spy gadget quickly fades when it turns out to be – lipgloss? There’s obviously been some kind of mistake at HQ, but while Connor is busy trying to sort it out, he runs into bigger problems. Jorge, the inept but lucky agent running the investigation into Ed’s recent actions, leaves both Gisela and the dangerous-but-harmless-looking gadget unprotected at school.

It’s bad enough that Gisela and Connor always have to double date so that Connor can protect Gisela, but to have to babysit Jorge, an inept agent, at the same time and keep him out of danger til his flight out of town? That’s asking a lot. Too much, as it turns out. When Jorge gets into a world of trouble, Connor and Gisela must ditch their annoyed dates and take care of spy-business.

When Mom and Dad leave town, Connor and Gisela throw a much-needed party. What could go possibly wrong? Well, they could accidentally set the high-tech house to 'self-destruct'. Faced with a tick-tick-ticking house and enemy leader Azul's men on the way to collect the rubble, Connor and Gisela need a new party plan, fast.
