We meet Vodi and Efna who live in the Neolithic village of Skara Brae in the Orkney Islands. They spend their days farming the land and hunting for food. Follow them through their day as they compare arrays of barley planted in a field, compare the number of fish Vodi catches to that of his dad, compare the amount of berries Efna collects compared to her mum and make statements complete when arranging food for the festival of the Summer Solstice.
