Helēna feels unfulfilled in her marriage to Rihards, a university lecturer. Together with their children Ēriks and Maija, they go to their house in the countryside to renovate it as Helēna hopes to soon be able to organise dance retreats there. More surprising than the dreariness of their relationship are the creatures that inhabit their forest house – fleshy caterpillars in the wallpaper, slithering worms on the dinner plates, and stag beetles on the damp walls. As the terror of the insects takes hold, Helēna and Rihards each take up positions on opposing front lines in a war that also uncovers the children’s phobias and losses they have not yet processed.
