Death by natural causes, suicide or murder. These are the only options Boyd gives Marina Coleman who is unable to put her father's death to rest. Marina is obsessed with finding the truth but Boyd is not sure she can take it. Boyd reluctantly takes on the case and finds that there's more to this murder than meets the eye.
Some old photographic negatives provide vital clues for the investigation. Then when the team exhume Perry Coleman's body the case takes on a macabre twist. DNA tests prove that either Perry Coleman is not Marina's father or that the body they've exhumed is not Perry Coleman.
When a skeleton is discovered in a Church crypt Boyd and his team suspect it was never meant to be found. The evidence leads them to believe the body is that of a blind man. The team interview the local community and awaken deeply hidden family secrets that force Boyd to look at his own past.
Frankie learns that the skeleton and a priest may be related as both show symptoms of Huntington's Chorea. The hunt is on for the killer and the victim's mother. Meanwhile, the investigation opens old wounds for Boyd, still in despair over the disappearance of his own son.
Twenty five years ago Annie Keel confessed to the murder of her husband, Jeff, and eight-year-old Giles Mantel, a neighbour's son. Annie was found covered in blood and holding a carving knife. The mere mention of Annie Keel's name strikes horror in the minds of the public - no one wants to face up to the idea that she might be innocent. No one, that is, except the Cold Case Team.
Boyd and the team now have evidence to show that Annie Keel might be innocent of the murders of her husband Jeff Keel and Giles Mantel, the eight-year-old son of a neighbour. If she's innocent why did she confess? Annie's own eight-year-old son, Sam, was there that night in 1975 - Boyd wants him found but nobody knows where he is or even who he is.
