A naked middle-aged man walks out of the sea and starts climbing the steep rocks of a deserted island. He walks through an abandoned underground tunnel and descends to a large, empty sandy beach where his younger wife and 6-year old daughter are waiting. Their mutual inability to communicate is witnessed by an interested but troubled woman who is fishing from a boat anchored near the beach. When the tension erupts into violence, three members of the family will become two, and finally – in the open sea – only one person remains, caught in the trap of their own emotions.
