More powerfully tense than many thrillers full of action and blood, this finds the terror in the small gestures of growing up, and the enormous implications behind them.
In the main story, adolescent Emma befriends cool girl Cassandra as they train to be part of a team that does gymnastics on horseback. Both friends and rivals, director Aschan manages to load almost every scene between the two with incredible unease. It seems as if at any moment they are either going to tear each others clothes off and make love, or kill each other, or kill someone else -- any and all combinations seem possible as they test their limits on the ragged edge of adulthood.
At the same time, Emma's 7 year old sister Sara is pushed by the world around her to become aware of her body with alternating pride, curiosity and shame, and her nascent sexuality leads to some wildly uncomfortable scenes with the adult men in her family. This never crossed the line into exploitation, but it effectively made me want to jump out of my skin, while making me ponder the deeper thematic and psychological/social issues.
One thing bothered me; the very end of the film seemed to over-simplify the mysterious complexity of much that had preceded it, reducing the story to something more pedestrian, and taking some of the considerable wind out of the film's sails. But this is still one of the better films about the terrors of youthful sexuality I've seen in a long while.
