After David Kim (John Cho)'s 16-year-old daughter goes missing, a local investigation is opened and a detective is assigned to the case. But 37 hours later and without a single lead, David decides to search the one place no one has looked yet, where all secrets are kept today: his daughter's laptop. In a hyper-modern thriller told via the technology devices we use every day to communicate, David must trace his daughter's digital footprints before she disappears forever.
It started slowly as the characters were revealed and like Nordic Noir the narrative drive was the meticulous investigation on the internet. For those on social media this was brilliant for those more technologically naive this was a bore. The silence and mouse clicks let to the suspense for me others thought it made the movie slow. The acting was brilliant and you felt his pain and frustration. A really great movie with an unexpected twist, I loved it.
