Three young teenage siblings find themselves confined to an isolated country estate. Their parents keep them on this compound to "protect" them. These three spend their days listening to countless homemade tapes that teach them an entirely new vocabulary. They soon create their own lingo from these tapes; assigning new meanings to almost everything. For example, 'the sea' is a large armchair and 'zombies' are little yellow flowers. Their parents even go as far as inventing a brother whom they claim to have ostracized for his disobedience. These super controlling parents are terrorizing their children into submission. The father is the only family member who is allowed to leave the manicured lawns of their self-inflicted exile. He earns his living by managing a nearby factory. The only outsider allowed inside their compound is the dad's colleague, Christina, who is paid to relieve the son of his male urges. However, Christina grows tired of all of this. So she begins to disturb the domestic balance.
