12-year-old gymnast, Tinja (Siiri Solalinna), is desperate to please her image-obsessed mother, whose popular blog ‘Lovely Everyday Life’ presents their family’s idyllic existence as manicured suburban perfection. One day, after finding a wounded bird in the woods, Tinja brings its strange egg home, nestles it in her bed, and nurtures it until it hatches. The creature that emerges becomes her closest friend and a living nightmare, plunging Tinja beneath the impeccable veneer of her family and into a twisted reality that her mother refuses to see.
