A simple story, full of nuances from its beginning, Hitchcock influence, realistic portrait of hustlers, a nice relation, discovered in its complexity, correct work, good acting, delicate subject, portrait and eulogy of loneliness , bitter , perfect end. A trip of two strangers. The precise purpose of the old one, the temptation to escape from his life circle of the other. And complex relation between them. Not great but, obvious, more than decent, beautiful for melancholia of story and for few inspired scenes. And nice for the courage of end , giving simple, precise message about a pain without cure.
