There's been a murder at the family run drive in movie theatre in Savannah Georgia. One person's dead, another injured and the movie case from the night's feature: "The Magnificent Obsession" has somehow disappeared. The police have no leads. Detective Rory Connor, son of the theatre owner, flies back from Ireland to help solve the crime only to discover a plethora of dangerous motives still lurking. Is someone running drugs through the drive in? Is the possibility of a cut throat real estate deal enticing the killer? Or, as unlikely as it might seem, has the annual competition for the position of Grand Marshall of the St Patrick's Day parade suddenly become more sinister and deadly? Along the way both help and hindrance comes to Rory from a variety of disguised and discredited sources: Arthur, an uncle who has a temporal dislocation and believes he's living in the world of 1959; Joe, a hot tempered disbarred lawyer; Maeve, Rory's fiery girlfriend from Ireland; Jenny, his long ago lover and Kevin, a bombastic philosophy professor who wants to build an Irish theme amusement park near Savannah. Can they unravel the mystery before another murder takes place?
