A drama centered on a group of people searching for human connections in today's wired world.

A former Marine (Alexander Skarsgard) reacts to his failing marriage by succumbing to the credit-sapping allure of online gambling, while his wife (Paula Patton) begins to confess her secrets to a stranger she's met on a social-media site. These cyber-transgressions result in stolen savings and stolen identities, leading the couple to seek revenge on the man they presume to be responsible (Michael Nyqvist) - but is he?

In a parallel story thread, a pair of teenage pranksters play a nasty trick on an outcast classmate (Colin Ford) - an introverted goth boy with genuine musical talent - by posing on Facebook as the girl they know he likes. Mercilessly stringing him along, they push the boy to expose himself online, a humiliation that leads to an act of desperation - which drives the boy's mother (Hope Davis) to inconsolable anguish, and his father (Jason Bateman) to uncontrollable anger. Meanwhile, a TV reporter (Andrea Riseborough) sets out to tell the story of another young man caught up in selling online sex, but is soon confronted with the impact the publicity might have on his safety.
