Can feuding divorce lawyers fall in love? Daniel Rafferty (Pierce Brosnan) and Audrey Woods (Julianne Moore) find themselves competing in a divorce case. The at-odds couple is fighting over a spectacular castle home in Ireland and their lawyers are forced to visit the estate together to determine its worth and come to an agreement as to who should receive the home in the settlement. They land in Ireland during one of the year's most romantic festivals and, after a night of platonic drinking, wake up to find themselves married. When they return to the States, they must "act" married in order to maintain their lucrative reputations. Will their pretend nuptial act turn into a real life happily ever after?
