Every lawyer, at least once in every case, feels himself crossing a line he doesn't really mean to cross. It just happens. And if you cross it enough times, it disappears forever. And then you're nothing but another lawyer joke, just another shark in the dirty water.
The movie is about the bizarreness when an old and lonely person faces the loose connection with his intimate ones, the life-time career and life-time families. But ends up being driven to continue living by building a new relationship with a far-away African orphan.
