In the UNESCO heritage landscape 'Acid Forest' (Curonian Spit National Park) where half of it belongs to Lithuania and the other half Russia, the film visualizes the fear and apocalyptic scenes that one might feel from 'The Birds' by Hitchcock. In the wispy grey forest live thousands of great cormorants, whose acid-fortified feces kill the 2~300 year old pine trees. People speak what they see and what they feel after looking around in the forest. The film shows the tourists from a bird's eye view. We hear their conversations and see the birds nesting on the thin trees. From dawn to dusk and even deep into the night, the camera looks up in the sky, day and night, periodically and rhythmically. Unlike other normal nature documentaries, this movie has a unique expression and different sensation in describing the problems of ecological imbalance.
