Poison is about two people trying to live with 'what is not there, but should have been'. Ten years after the death of their child, a man and a woman meet again for the first time. They have been informed via a letter that there will be a reburial due to poison in the soil. He has built a new life. She cannot bear the thought of a new life. During the few hours they spend together, they feel each other out, and it becomes clear how the great loss has poisoned both of their lives. In an intense dialogue, they continue to search for that one word; that one movement in which the past could find peace.
