The Tracey Fragments (2007)

Tracey, 15, searches for her young brother as a blizzard threatens to take over Winnipeg. Her telling of the circumstances she finds herself in (wearing only a shower curtain on a city bus) is told in loose fragments and the film reflects this by dividing the film frame into numerous angles and scenes. Watching the film is difficult because of this, but at the same time it's an interesting way of looking at a subject like memory. 

The subject matter is also quite disturbing as there is quite a lot of abusive behaviour and little hope. Ellen Page brings a high level of pathos and autonomy to her character.
