Actress Anne Reid was close to her father but knows very little about his family. She only has a couple of clues to go on - the name of a house in Scotland and a family story that her father's side were ministers in the church. These clues soon put her on the trail of her great-great-grandfather John Reid - not a minister at all, but a schoolteacher in Fife with a sideline in forgery. When John's forgeries land him in the dock his life takes an unexpected turn - to Tasmania, on a convict ship.
