A young gymnast, who tries desperately to please her demanding mother, discovers a strange egg. She hides it and keeps it warm, but when it hatches, what emerges shocks them all.

Desperate to please her domineering, image-obsessed lifestyle vlogger mother, fragile 12-year-old gymnast Tinja finds herself between the hammer and the anvil. But nothing is ever good enough, and as Tinja struggles to hone her skills, slowly succumbing to the insufferable burden of expectations and perfection, an unexpected finding in the woods becomes the silent harbinger of violence. Now, the thing in Tinja's bedroom threatens the unsuspecting family's well-tended illusion and mum's fake picture-perfect reality. And to think that wide-eyed Tinja would do anything to impress her passive-aggressive mother. What has Tinja been hatching under everyone's noses?—Nick Riganas

In Finland, the middle-class family of the gymnast Tinja seems to be perfect in the Vlog of her mother. However, she is an overbearing mother that forces Tinja to overwork in the gymnastics to win competitions; her husband is a cuckold, and she cheats him with the handyman Tero; and her son Matias is envious of the attention his mother gives to Tinja. When the next-door girl Reetta befriends Tinja, her mother becomes jealous since Reetta is better gymnast than Tinja. One afternoon, a crow enters the living room of the family and breaks many objects, but Tinja captures the bird with a towel. However, her mother breaks its neck and Tinja drops the bird in the garbage can. Later, she finds that the bird was not dead, and she is forced to kill the crow to put it out of its misery. She finds an egg nearby the crow and brings it home. She notes that the egg grows incubated below her pillow and inside a teddy bear later but soon the egg hatches into a bizarre bird-like creature. Tinja raises and is connected to the creature that is her alter-ego for evil desires that Tinja hides in her apparent perfect world.—Claudio Carvalho, Rio de Janeiro, Brazil
