This is a film about the good and the bad, child neglect, illness, wrong angels, fallen angels, faith, fear, trust, self-worth vulnerability and childhood in general. I intentionally didn't incluide sins in this list. Angels can fall for various different reasons, even bad luck. It uses a lot of christian metaphor. But I wouldn't call it religious as a whole.
Two sisters of roughly 9 and 5 years, a father who works a lot and a mother who cries a lot make up this poor family. The two children are amongst themselves most of the time. The older sister, Angela, takes the lead during everything they do together. She uses religious rituals to hold on to sanity and innocence, to banish the devil and to entice good angels to make her mother happy again. At home they encounter various chances of enriching their collection of childhood traumas. During their one-day adventure of running away after their mother is hospitalised they meet very different people for short amounts of time. In some cases you wish they had had more time to become better friends; in another case you can't believe their luck that cut their encounter short. In the end, though, they only have each other - and god, if you believe in that.
This movie plays with the feelings of the viewer. It builds up empathy quickly, then slowly destroys any good thing that may be carried by it. It pokes at your heart, pushes it around, only gently enough to keep you watching until the end.
