On the night before Lane and Zach get married, the plans for a bachelorette party go awry, as do the plans made by Zack's buddies, so the two groups end up together for a makeshift party in the basement of Brian's aunt's house. Mrs. Kim informs Lorelai that she cannot attend Lane's wedding without an escort. Since Luke is still out of town, Lorelai invites Christopher to be her date. Everyone attends two wedding ceremonies, followed by a wild wedding reception in the town square.
