Revanche

Revanche is a film by Austrian writer-director Gotz Spielmann

Revanche is about human loss, and how it makes us more human sometimes. The film begins with a reflection of trees in a pond. The stillness of the nature suddenly shatters by tossing out an object into the pond. It creats a shocking moment when widening ripples develop a poetic sense of mystery.

The last scene. 

And the few more scenes.
