A man wearing an expensive gray suit finds himself in Central Park in New York City not knowing who he is or how he got there. His amnesia even extends to the fact that he doesn't know how he takes his coffee. All he has on his possession are a crumpled piece of paper wrapped around a couple of pills, the paper also with a scribbled telephone number. He is also wearing a ring with a broken stone, the ring engraved from its giver with his or her monogram, G.V. The telephone number takes him to a woman who doesn't know who he is. Based on what she calls him and some item association, he begins to call himself Sam Buddwing if anyone asks him. As he wanders New York City in a daze, he believes he may be an escaped mental patient based on a newspaper story, his clothes and the monogrammed ring. But a vision of a young brunette makes him remember a woman in his life named Grace. He manages to spend time with a few women during the day, many times he believing that woman is Grace herself. His time with these women triggers happy and not so happy memories of Grace. Time with one of the women who he knows is not Grace may provide the strongest trigger to remembering who he and Grace are and why he was in Central Park in such a despondent state.
