When both Will's and Grace's boyfriends, McCoy and Noah, ask them to move in, Will and Grace use each other as their excuse to get out of it. Meanwhile, a snowstorm keeps Karen at the office, where she meets Nikki, a woman who works upstairs. The storm also traps Jack in an elevator, causing him to reunite with an old flame, Drew, that tests Jack's commitment to a monogamous lifestyle.

Jack and Estefan's romantic wedding in Spain takes a detour when their flight is cancelled, forcing them to get married at the airport by their friend Miss Coco. McCoy's big job offer in London has Will worried about engaging in a long-distance relationship. While dealing with doubts about her current relationship, Grace meets a charming guy (guest star Reid Scott) at the airport who inspires her to make an impulsive decision. And advice from Smitty makes Karen reconsider her commitment to Nikki and her own sexual orientation.
