Long before Dr. Fingal Flahertie O'Reilly came to the colourful Irish village of Ballybucklebo, young Surgeon-lieutenant O'Reilly answered the call of duty to serve in World War II. As a ship's doctor on the HMS Warspite, Fingal faces danger upon the high seas. With German bombers a constant threat, the future has never been more uncertain.

But even with all that occupies him in the present, can O'Reilly ever truly let goof the ghosts from his past?
