Caitlin O'Conner, now 21 and in her senior year of college, accepts Josh Miller's proposal for marriage. But Caitlin soon discovers there's a lot more to getting married than just saying "I do." Between her mother and mother-in-law to be (who don't seem to agree on anything) and Caitlin's old buddies (who still have problems of their own because of wrong choices), Caitlin's life never seems to run smoothly. But Caitlin, as determined as ever to do things God's way, always manages to find the high ground...eventually. As a result, the journey to her wedding is full of twists and turns where God touches many lives, including Caitlin's. Most of all, Caitlin and Josh realize that a wedding only lasts one day, but a marriage is for a lifetime.
