Who’s that knocking at my door?
Things get tense when a couple vacationing on a remote island off the coast of Scotland rescue a badly-hurt man who claims the rest of the world has gone to Hell thanks to the sudden emergence of an airborne virus.
Once the trio are barricaded in the only house on the rocky retreat, things get progressively worse.
The visitor, played by a menacing Jamie Bell, grows increasingly more dangerous, while the couple — whose relationship was already deeply-fractured — let their paranoia run wild.
A smart lil’ mystery which spins its webs of intrigue with care.
