When the mother (Nia Long) of a typically social-tech-savvy 18-year-old LA girl whose dad died a decade earlier goes missing while on vacation in Colombia, young June (Storm Reid) makes creative use of her only resources: online apps, texting, security cams and navigation programs. But her sleuthing turns up more questions than answers. Nice turn by Joaquim de Almeida as the cut-rate Colombian private eye she hires online.

This is one of those films that takes place entirely on a computer screen, so you’ll be doing as much reading as watching. But don’t pass it off as YA fluff.
