It's another ordinary Friday night in the suburbs for the Garcia-Jackson family: Mateo and Valentina's favorite show is on TV. Mateo's best friend, Booker, is over. And their babysitter, Jennica, is definitely keeping an eye on them and not playing with her phone.

But when Elvis, the family's dog, bolts out of the house, barking uncontrollably at someone--or something--in the backyard, the kids go investigate...only to watch Elvis disappear through a mysterious portal!

The three kids, with their babysitter in tow, have no choice but to follow him--adventuring through deep space, where they'll encounter aliens, dodge asteroids, and defy gravity--as they attempt to find their furry best friend (and make it back home before bedtime!).
