Rules Of Engagement feature two couples and their single friend dealing with the various stages of dating, commitment, and marriage. While Adam Rhodes and Jennifer Morgan (Oliver Hudson and Bianca Kajlich) begin their lives as a newly engaged couple, Jeff and Audrey Bingham (Patrick Warburton and Megyn Price) muddle through their long-time marriage. Meanwhile, single friend Russell Dunbar (David Spade) works his way through serial dating and a string of one-night stands. The group is later joined by Dunbar's assistant Timmy (Adhir Kalyhan), a single-but refined young man who attempts to serve as his boss' moral guide.
