When Dharma and Greg throw a party to celebrate their union, a disapproving Kitty boycotts the event, and Dharma sets out to befriend her mother-in-law. But when the Montgomerys and the Finkelsteins finally get together to plan the details, the hostilities really begin.

Dharma tries to sprinkle a little TLC in Greg's life by installing a new, deluxe ""Spring Mist 3000"" shower, while Greg finds himself on a testosterone-ridden golfing afternoon with Edward and Larry. Meanwhile, Kitty, misunderstanding the word ""shower,"" readies for a social event with hors d'oeuvres and formal invitations.

There's love amid the ruins when Dharma and Greg hold a ""do-over"" wedding to appease their families, particularly the hostile Kitty, who turns the young couple's plans for a simple party into a big country-club affair, including a formal renewal of the wedding vows. (Says Greg to Dharma: ""You know, some day our parents will be gone and we'll look back on this day and not miss them so much."") Meanwhile, Pete and Jane have a surprising encounter of their own in the cloakroom.

Election day is here, and Dharma has finally mastered the art of politics. But it's her own body that teaches her that lying can lead to flu, rashes, eye sties, oozing sores and even a bout of the gout.

Dharma and Greg join their parents, and even Pete and Jane, on a couples' retreat. But when they repeatedly fail tests designed to demonstrate the strength of their relationship (while Pete and Jane score tops), they resort to covert measures. Meanwhile, Kitty and Edward find a weekend in the wild to be just that.

For the first time in her life, Dharma gets depressed about her sex life when she discovers that Greg can't make a move in the bedroom without checking his day planner first. Meanwhile, a depressed Greg confides in Pete, who convinces him the only logical explanation for the downturn in his sex life is that Dharma is seeing someone else.

Dharma's ritual of unburdening her sins every seven years reveals things that would be better off remaining a burden. Meanwhile, Larry convinces the Montgomerys' maid, Celia, to go on strike, leading everyone to discover how much control Celia has over Kitty's personality.
