In Britain today, more than six million of us employ domestic help in the form of cleaners - a job primarily done by the scores of immigrants arriving in the UK looking for work. What do the contents of our homes and our interactions with a workforce paid to clean up after us reveal about us? With access to cleaners and their clients, this documentary lifts the lid on what our cleaners really think about us. It also tells the story of an invisible class struggling to earn a living and make a life in the UK.
