In the first episode of "The Lost Fleet," Ash sees someone fall from the top of a spaceship and she starts running. She doesn’t ask questions until she’s in a spaceship of her own and heading for the moon. The girl who fell won’t give her real name, but she knows how to fly and she’s definitely not from Earth.

Ash and three other high school students find themselves in charge of ships so old they were buried on Earth with the dinosaurs. Not all of them work the way they're supposed to, but they make it to the moon. The girl who fell promises to help repair the ships if Ash can keep adults from taking them back.

Restoring the ships will be difficult. Protecting them will be even harder.
