Sweet November

Nelson Moss is a workaholic advertising executive who meets Sara Deever, a woman very different from anyone he has met before, at the DMV. His attempt to get an answer from her on his driving test leads to her failing, as the instructor sees their interaction and believes it is she who is cheating.

Sara beguiles Nelson and continually asks him to spend a month with her on the promise that she will change his life for the better. On the first night of November, after he is fired and dumped on the same day, she sleeps with him, and the next day Chaz, a close friend and neighbor of Sara's, arrives and refers to Nelson as Sara's "November".
