After an unspecified event that has apparently cut most lines of communication except radio, a family leaves town to go to their weekend home. But the weekend home has been invaded by another family, and the father of the family is killed by the squatters, who take the family's supplies and shelter, forcing them to move on nomadically through the countryside. They meet a young boy who steals and raids corpses for whatever he can scavenge and then join a group of people waiting at a railway station for a train to take them somewhere else.
This is an end of the world story, but it eschews Mad Max style action to look at human reactions, from the mother slowly coming apart, to the daughter who fights on, to the young boy who suffers in silence. The world quickly loses its laws and its justice and life becomes squalid. And so the story feels realistic, feels like this is how things would go if the world ended. Which of course means that it is also a microcosm of our life today.
It's a dark little tale, which only shows a little hope in the human kindnesses that are done. It's rife with little biblical touches, and the sudden explosion in population suggests it is also human history potted into a little under two hours.
If you want laughs or action, you won't get it. But if you want a human drama, intended to make you think about how we live our lives, then you should be pleasantly surprised.
