Underlife - short animation from Studio Munka, directed by Jarosław Konopka.

The film talks about birth, coming and going; whether a person can break free from under the influence exerted on one's life by the time and place of birth, and by the event of turning up in one's own pram. And whether one is aware of the invisible, sometimes destructive, influence of our ancestors, which might result in one never being able to leave this pram.
It is a symbolically metaphorical short story of one such pram, inspired by Lullaby/Kolysanka by Krzysztof Komeda, among others.
