“Kokoro” is a concept that the heart, mind and soul are at one and problems arise when they behave as three distinct elements. Kokoro follows three scientists: a doctor father, his psychiatrist daughter, and his machine learning son, who became emotionally distant when the matriarch of the family died years ago. When the father gets suddenly ill, all three must re-unite to figure out his diagnosis, overcome their differences, and become the complete family they once were. Kokoro is a family drama that examines scientists’ relationship when faced with “the undiscovered country.”
