In season two, a resourceful and courageous Gabby faces even bigger challenges as she continues to protect her alien charges while also navigating the everyday emotional rollercoaster of middle school. The season picks up immediately after a cliffhanger with Gabby's mom, Dina, on the verge of learning Gabby's secret, which the intrepid teen will have to stop in order to avoid catastrophic outcomes. Other adventures this season will include a robot replica Gabby-bot running amok, an alien friend who turns into a "Predator" when she becomes emotional, and a quest to recover Principal Swift's home after it's shrunken down to the size of a dollhouse by an extraterrestrial prankster.

Gabby Duran constantly feels like she's living in the shadows of her uber-polished, successful mother and whip-smart younger sister. She finally finds her moment to shine when she inadvertently lands an out-of-this-world job to babysit an unruly group of very important extraterrestrial children who are hiding out on earth with their families, disguised as everyday kids. Fearless and unapologetically bold, Gabby steps up to the challenge to protect these youngsters and their secret identities, and prove she's the best babysitter in the galaxy.
