It would be easy for the story of an ageing former prostitute who looks after the children of other prostitutes, and who forms a bond with a young Senegalese boy, to be a little too saccharine. In the hands of a lesser director, or a with a lesser cast, that might certainly be the case. As it stands the film toes that line but doesn’t cross it, thanks largely to Sophia Loren and young star Ibrahima Gueye.
