On the day of Molly and Irving’s wedding the usual hiccups and snags happen, but Irving’s best man, chemistry professor Everett Donnelly, is there to smooth them over, keep everyone organized and make last minute adjustments based on the lists he keeps. If only he weren’t distracted and reeling from his strong attraction to Molly’s brother, police officer Jake Mountbatten, whom Everett first met at the rehearsal dinner. In between boutonnière crises and wedding photos, the two men have ample opportunities to catch each other’s eye, but the obligations of the wedding interrupt them time and again. Finally, all the speeches and traditional activities are over, and Everett finds Jake to see if they can make a little romance of their own.
