An Afro-American actor (Jamie Foxx, I think) plays a radio host. His show keeps getting calls from an anonymous listener and he wants to find out who is it and why does it do it. He will have a lead on the stalker by recognizing a cigarette brand logo on a fag that he finds in his lawn and connecting it with some acquaintance of his. The film finishes very undefined, very abstractly, with a scene where an unrecognizable woman invites him to join her in the white bed where she lays covered in white sheets. During the film, the host at one point plays a song that is dedicated to this stalker and its title is something like Night Stranger or similar.
