Soon the two lawyers are pitted against one another in several high-profile divorce cases, including a nasty public split between rock star Thorne Jamison (Michael Sheen) and his dress-designer wife, Serena (Parker Posey). The settlement hinges on an Irish castle, Caisleán Cloiche, or "Rock Castle," that each spouse wants. Audrey and Daniel travel to Ireland to chase down depositions, and both stay in the castle. Although Audrey, at least, is reluctant to acknowledge their mutual attraction, they find themselves attending a romantic Irish festival together. After a night of wild celebration, they wake up the next morning to discover they have wed. Audrey is shocked, though Daniel takes their apparent marriage in his stride.
