Tuck, Munch and Alex are nerdy best friends but a roadway is being built through their Vegas suburb and their families have to move. Then they find their phones acting up. They figure out the image on their phone is a map and they find strange pieces of metal. As they collect each piece, they connect to form Echo. One of the locations turns out to be popular girl Emma's home. She insists on joining them as they continue collecting pieces. Also the road construction crews led by Dr. Lawrence Madsen (Jason Gray-Stanford) seem to be aware of something going on.

It starts as the Goonies with smart phones. They find a mechanical ET. The story is perfectly fine. The kids are OK but Tuck talks too much. The two other boys don't get enough attention. My big problem is the found footage style. The shaky hand held camera is too shaky. It needs to compensate with regular camera work especially in some of the action scenes. They could be done so much better. It could have been a good kids adventure.
