A remote Scottish estate. A missing teenager.
When a young archaeologist discovers bones at the site of her Bronze Age Broch on Gallows Hill, the community of Kilbroch hold their breath. A post-mortem on the remains reveals that the body is that of teenager, Robbie MacBride, missing for more than a decade. The teenager was shot at close range, and his gamekeeper father falls under suspicion. However, not everyone is convinced.
The archaeologist, Laura, ex-detective, Callum MacGarvey and Robbie's grandmother continue to investigate, while Robbie's sister, the silent Ruthie, remains haunted by her inconclusive childhood flashbacks. Local landowner, George Strabane is arrested, Robbie's father is released, and it seems that old ghosts have been put to rest.
However, the truth is darker still and the tragic reason for Ruthie's self-imposed silence is finally revealed.
