Dogtooth (2009)

Plot

Three siblings live in a remote estate, cut off from the outside world, where their parents impose strict control over their lives. They spend their days absorbing homemade audio tapes that introduce a bizarre vocabulary, completely disconnected from reality. For them, 'the sea' is merely a large armchair, while 'zombies' refer to innocuous yellow flowers. The parents manipulate their children’s understanding of the world and fabricate a story about a brother they banished for disobedience. This oppressive environment fosters a twisted sense of reality, leaving the teenagers trapped in their manufactured existence.
