Question...
English is not my first language and British accent is almost impossible for me to understand, so I did not get a lot about the movie (will try to watch it again ).
But one thing I would like to understand: what is exactly that they do ?
They just bring up to light some embarassing moments from people's lives and expose their secrets ? After the "cleaning" is like they testify that no other secret is being hidden ?
And why, after leaving a client's house, one of the cleaners say to the other : "Those people have no idea how lucky they are " ?
