After arguing with her live-in boyfriend about his inability to commit, Peggy Adams flies to a friend's bachelorette party in Las Vegas, and wakes up next to a man she can't remember. Hung-over and miserable, she sneaks out of the sleeping man's hotel room and returns home to New York, where her boyfriend apologizes for the fight and gives her a Tiffany box containing a pre-engagement ring.
Not what she expected, but close enough! The next day she receives a phone call from the Las Vegas one-night stand, Luke, claiming she's already married to him and he faxes her the license for proof! Both are ready for an annulment, until Peggy arrives in quaint New Nineveh, CT, where Luke cares for his Great Aunt, and the old woman makes Peggy an offer she can't refuse.
