Ronan Sullivan is a popular author who needs a place to write without interuptions. Deirdre Patten, a single mother of two rambunctious boys, needs the money her apartment would bring but she doesn't want to rent to a man. Her ex-husband's cruelty has left her gun-shy. Ronan remembers meeting her at a company Christmas party several years ago when she was pregnant with her second child and her husband was drunk and couldn't care less how she got home. Ronan helped her into a cab and has never forgotten her. Deirdre doesn't know that Ronan is a popular author and of course there is the usual misunderstanding when she finds out. They have a wild encounter on her front porch practically the first night Ronan is there but they can't seem to keep their hands off each other. He is kind, considerate and takes to her boys. That encounter leaves her pregnant and they must decide what to do. He is the typical dumb guy who makes a marriage proposal based on how good they are together, etc. He has to learn to say those three little words before Deidre says yes.
