No amount of training could prepare Eva for what she’d find beyond her bunker walls.

Apple TV+ revealed the trailer for the animated adventure trilogy “WondLa,” hailing from Skydance Animation and based on the New York Times bestselling book series “The Search for WondLa” by Tony DiTerlizzi.

Showrun and executive produced by Bobs Gannaway and featuring a star-studded voice cast, the seven-episode first season of “WondLa” will premiere globally on Apple TV+ on Friday, June 28.

“WondLa” centers around Eva, voiced by Jeanine Mason (“Roswell, New Mexico”), a curious, enthusiastic and spirited teenager being raised in a state-of-the-art underground bunker by Muthr, a robot caretaker, voiced by Emmy Award nominee Teri Hatcher (“Desperate Housewives”). On her 16th birthday, an attack on Eva’s bunker forces her onto the Earth’s surface, which is now inhabited by aliens and covered with otherworldly fauna, and there are no other humans to be found. In fact, it’s no longer called Earth, but Orbona. Otto, a lovable giant waterbear with whom Eva shares telepathic powers, voiced by Emmy Award winner Brad Garrett (“Everybody Loves Raymond”), and Rovender, a cantankerous alien with a troubled past, voiced by Gary Anthony Williams (“Teenage Mutant Ninja Turtles: Out of the Shadows”), join Eva as she leads the team on a dangerous quest to find humans, her home and her true destiny.
