Following a day in the life of Clarabelle， one of 1，200 cows on a Wisconsin dairy farm， we learn what it takes for a cow to produce life-giving milk and also by-products like electricity. The manure that Clarabelle and her herdmates create not only generates electricity， it provides fresh bedding for cow stalls and fertilizer for the crops grown to feed the cows. Vibrant close-up photographs capture Clarabelle， her calf， and the youngest members of this multi-generational farm family， Josh and Sam， sharing the workload.
