Zeke Zander and his family are aliens from Planet Z. So when their spaceship crashes on earth, they must pretend to be humans until they can fix their ship and return home. But with antennae on their heads and a talking cat named Zeus, fitting in is easier said than done! Still, Zeke manages to become friends with some Earth kids, and Zeus even stars in a cat food commercial. The money Zeus earns goes toward fixing the ship, but the Zanders soon realize that the repairs will take a really long time. As Zeke settles into his temporary home, he wonders if he can truly be the only kid from Planet Z trapped on Earth.
