In 1975, 11-year-old Andrew Conroy was brutally murdered, his body hidden under a bush in a dense woodland area known as The Dell. The detective who headed the investigation, now in his late sixties, has felt guilty ever since that he was unable to solve the murder case. Each year he asks his son to drive him to The Dell so he can wander through the overgrown woodland in the hope he will find the clue that will solve the mystery, but each year to no avail...until now.
