Bird's only way out of the apartment is to fall in love with Silesia and leave her to be the apartment's new muse and victim. Birdsong is a haunting, heartbreaking, retro-cinematic time loop experience in a magical, twisted apartment that asks the ethical question of choosing love or personal freedom when time is never on your side.
