After learning from Sam’s sister that he doesn’t plan on ever getting married again, Cassie takes a sojourn to Chicago to clear her head and meet with an old friend. When Sam finds out, he impulsively (and uncharacteristically) heads off to track her down. Meanwhile, the wedding planning has gotten out of control – Michael and Vanessa are fed up with their overbearing mothers and decide to call the whole thing off. When cooler heads prevail and the town rallies together to pull off the lovely and simple ceremony the bride and groom desire, Sam and Cassie find themselves face-to-face with their own future...

Cassie discovers a 10-year-old girl – Pavla – playing in the bushes at Grey House. She is hiding from her adoptive parents, Eddie and Marla, who could use a little help from Cassie and Abigail as they forge their new family. Meanwhile, Martha announces that her son Michael is getting married. He and his fiancée Vanessa want a simple wedding, and Martha needs some gentle reminders from Cassie to not go overboard. And Sam’s sister Joanne shows up for an unexpected visit and he is very happy to see her, though she does not seem like herself...
