Basically E.T. + Batteries Not Included + Stand By Me in found footage form
A tale of innocent friendship; three kids embark on a secret adventure together, find a robot owl-like alien, make friends with it, try to prevent it from authorities' reach and intend to help it go back home. Sounds very, very, very familiar? Well, as said on the headline above, it's 'cause it's very, very similar to Steven Spielberg's E.T. the Extra Terrestrial (1982), Batteries Not Included (1987), elements of Stephen King's Stand By Me (1986) and maybe J.J. Abram's Super 8 (2011) as well, but completely through the eyes of camera devices.
