While Isabel is babysitting her three-year-old half brother Tommy at the park, the unthinkable happens: she takes her eyes off of him for only a moment, and he vanishes. Losing Tommy creates a rift between Isabel and her parents, made worse with the revelation that the photos at the park that she posted led the kidnapper to him. Isabel launches her own investigation by tracking geo-tags, starting a game of virtual cat and mouse as Isabel tries desperately to save Tommy before he's lost forever.
