Earth To Echo starts off as a video diary about the last day that three best friends/neighbors spend in their suburban Nevada development, which is being destroyed to make room for a new freeway. When camera-loving Tuck (Brian "Astro" Bradley) and his two closest pals, foster kid Alex (Teo Halm) and nerdy introvert Munch (Reese Hartwig), notice that everyone in the neighborhood's cell phones are all showing strange shapes, they decide to investigate. They pretend to sleep at one another's houses and head out on bikes to a nearby desert that looks just like the shape on their phones. In the middle of nowhere Nevada, the kids find nothing but a dusty metal capsule that they think is nothing -- but still take with them. Then, on their ride back home, Munch feels the backpack moving and freaks out. Some digging into the capsule reveals a tiny neon-blue-eyed alien who's communicating with their phones by delivering maps to the locations of his missing metallic parts. The boys name the alien "Echo" because he can imitate their sounds with little beeps, and together they embark on an all-night adventure to help Echo find his spaceship.
