After arguing with her 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 pre-engagement ring. Not what she expected, but close enough! The next day Peggy receives a phone call from the Las Vegas one-night stand, Luke, claiming she’s already married to him — and he has the paperwork to prove it! Both are ready for an annulment, until Peggy arrives in quaint New Nineveh, Connecticut, where Luke cares for his Great Aunt, and the old woman makes the reluctant couple an offer they can’t refuse.
