Elated to finally have found a bride in bossy Gretchen Palmer, goofy nerd Doug Harris, who never had a proper adult social life, got caught in his own lies about suitable friends as best man and seven groomsmen with unfortunately detailed characteristics. Doug's gay Mexican wedding planner, who fears a no-show in a few weeks, discretely refers him to Best Man, Inc., the private agency of slick bachelor Jimmy Callahan, who helps men trough daunting weddings for a living, yet considers this case an unprecedented-daunting 'golden tuxedo'. Still, paranymphs are recruited and like the groom trained intensively for their parts. Doug and Jimmy, whose character is army chaplain Bic, meet the Palmer future in-laws, and are dares to an American football match which proves less then friendly, in fact as painful as masked-abducted Doug's wild bachelor party, yet some bromance also blossoms. Still, hearing the unromantic truth from the bride's mouth on wedding day proves the crucial obstacle.
