Chef Ean Callaghan, brother of bride Ava, cheerfully volunteered as 'best man' to help prepare her Christmas-theme wedding in the family's traditional snow lodge in Wallowa Lake, Oregon, especially the appended cottage, believed to work some wedding as well as seasonal magic.
He does so together with the bridesmaid, San Francisco based workaholic interior designer Lacey Quinn, whose boss and fiance, ambitious architect Roger, almost persuaded her to cancel as they are working on a hot concept to combine work and family life in a single house.
She didn't count on and initially resents collaborating with Ean, her ex, but he soon smooths things and rekindles happy memories, especially while their are forced to spend the first night together, snowed in.
Their past gets talked through and each considers options for the future, possibly as a couple, and Roger's workaholic arrival makes Lacey remember there's more to life.
