The film begins with the destruction of Earth and then jumps back in time. The story is about two sisters, Justine and Claire (Kirsten Dunst and Charlotte Gainsbourg), who are becoming increasingly distant from each other. There is a wedding during the first part of the film between Justine and Michael (Alexander Skarsgård). Soon after the wedding Justine becomes melancholic, which makes her stay calm when Earth is threatened by a collision with another planet that has recently emerged from behind the sun, while Claire, on the other hand, becomes fearful of what is to come. Trier has said that he considers all of his previous films to end happily, and that this will be the first with an unhappy ending. (Wikipedia)
