Forced to attend a party hosted by someone she doesn't know, Anna doesn't even try to have a good time; she's just waiting for the right moment so she can sneak out unnoticed. The wrench in her plans turns up in the form of Jamie, a friend of a friend of the host, and despite her best intentions, he convinces her to get to know him and she definitely likes what she sees.
They take off early and head to Jamie's apartment for a private after-party, but a sudden family crisis forces Anna to leave before they have the chance to get started; it takes her a few days to realize she doesn't have his address or his phone number or his last name. Her disappointment is crushing, but she's left with no option but to try and move on with her life.
The appearance of a new tenant in the vacant apartment next door to hers is the last thing she needs, but she soon changes her mind when she discovers who her new neighbor is...
