Follows three Australian families in crisis as they embark on a world first experiment led by two elite psychologists. Can scientific tools make the families happier?
The families learn the power of both kindness and positive stress. The McDonalds face crisis and threaten to withdraw, while financial worries affect the Watsons. The Camerons are at loggerheads over parenting.
The families are in the final stretch. Stress levels rise, and resentments explode. John and Clare struggle to ensure that all the families see a rise in their happiness levels. Will the experiment succeed?
