The work of an organisation dedicated to revisiting forgotten cases, giving a name and a story to each unidentified person. Ex-detective Dave Grimstead and his team investigate the disappearance of George Johnstone - who vanished off the Norfolk coast in 1984 while on a family holiday. George selflessly entered the sea to help a family in distress, but tragically was never seen again. Now, George's family seek Dave's help to try and find his final resting place. It's a journey that takes the team in unexpected directions, as they enlist the help of a pathologist, a forensic oceanographer and an expert in facial reconstruction
