The film could just as well have been called "Where there is room in the heart, there is also room in the house," because it is actually about an old, seasoned people person's solution to the housing problem. He solves it in his own – admittedly unusual – way, but he solves it! Had he been a little more discreet, his invention would never have been discovered – and he could have lived the rest of his life carefree. But this experienced judge of character – whom we call "the Professor" – had one major flaw: his overly big heart for the small and unfortunate members of society in general and the homeless in particular. It is this unfortunate heart that sets the film in motion and accelerates the events.
