Two teenage sisters (Ellen Page and Evan Rachel Wood) struggle to survive in a remote country house after a massive, continent-wide power outage, in this gripping apocalyptic thriller from director Patricia Rozema (Mansfield Park, I've Heard the Mermaids Singing).

In a not-too-distant future, sisters Nell and Eva find themselves shuttered in their home. Surrounded by nothing but miles of dense forest, the sisters must fend for themselves using the supplies and food reserves they have before turning to the forest to discover what it will provide. They are faced with a world where rumour is the only guide, trust is a scarce commodity, gas is king and loneliness is excruciating. And yet somehow miraculously, love still grows.
