Though equally respected in their field, divorce lawyers Audrey Woods (Julianne Moore) and Daniel Rafferty (Pierce Brosnan) are opposites inside and out of the courtroom. Audrey is meticulous and by the book, while Daniel relies on personality and luck to get by. Despite the difference in methods, neither lawyer has lost a case, and neither plan on ending their streak after being respectively hired by Serena (Parker Posey) and Thorne (Michael Sheen), a celebrity power couple gone wrong. The divorce settlement hinges on a particularly spectacular Irish castle, which both parties would like to keep for themselves. Audrey and Daniel hurry to Ireland with depositions in their eyes, but a growing mutual attraction manages to squirm out from beneath, and, after being immersed in a romantic Irish festival, the rival lawyers wake up married. Reeling, potentially in love (to Audrey in particular's dismay), and faced with the type of media explosion capable of leading to the end of their careers, the mismatched lawyers contemplate how to go about their clients' divorce hearings as man and wife.
