In the heart of County Kildare is Davenport Hall – a crumbling eighteenth-century mansion house, ancestral home to Portia Davenport, her beautiful younger sister Daisy and their dotty, eccentric mother, Lucasta. Disaster strikes when their father abandons the family, cleaning them out of the little cash they had managed to hold on to. But a ray of hope appears when Steve Sullivan, an old family friend and confirmed bachelor, suggests that they allow the hall to be used as the location for a major new movie.
