Meg and Ash are a pair of magpies who are building a nest for their perfect eggs. Although they begin their nest construction using the usual mud, sticks and grass, Meg and Ash are soon convinced that their nest doesn't have enough stuff and begin to collect more things to add to an ever-growing pile. From cuckoo clocks to mops and socks, a pram and even a car - their need for stuff seems endless. Until - crash! - the inevitable happens.
