Ursula Heinzelmann, Germany's most renowned cheese expert, embarks on a world tour. She travels from Brandenburg to the Allgäu, across the Alps to Italy, and further to Anatolia, Ireland, Norway, California, and Vietnam. She meets people dedicated to the ancient craft of cheese-making. In Anatolia, she learns about cheese production in the nomadic style, using a method that has remained nearly unchanged for thousands of years. In Marin County, north of San Francisco, she encounters the legendary "Cowgirls," who have sparked a cheese revolution with their creamery. In Ireland, she meets a PhD specialist in Heidegger who has become the country's best cheesemaker. However, cheese-making involves not only people but also the animals and landscapes in which they live. Does the goat in the pen in front of the house produce different milk than her sister who lives outdoors all summer?.
