Hidden - (2015)
A couple and their their young daughter have holed up in a fallout shelter from the apocalypse - surviving 301 days, despite nerves fraying and heavy fatigue. On their 302nd day they are beset by disaster after disaster as they realize their time is running out.
If you like the sound of the above you should really check out Hidden. For the first three-quarters the film doesn't have one single misstep, with a taught atmosphere it builds up to a climax that is probably impossible to please every viewer, or even most viewers. The Duffer brothers, who wrote and directed this, would go on to create the Stranger Things TV series.
