For 80 years, the O'Connors have battled what they believe to be a miscarriage of justice. Small time criminal Jimmy O'Connor was arrested for the murder of 'Donk' Ambridge and narrowly escaped the noose.

Fast-forward 25 years and Jimmy is living a wonderful life on the Greek island of Mykonos. Now a sought after TV scriptwriter, he rubs shoulders with The Rolling Stones and Jackie Onassis and entertains the great and the good with his wife Nemone Lethbridge, one of the UK's first female barristers who defended the Kray twins.

Yet the shadow of his conviction looms large over them both. His son, Ragnar O'Connor, along with his brother Milo and their 93-year-old mother are intent upon trying one last time to finally get to the truth.
