3 small children leave their small Dublin neighborhood to play in the woods. Hours later, they find 1 child, gripping a tree trunk in terror, unable to recall anything of the previous hours.
20 years later, the 1 found child is a police detective charged with investigating the murder of a 12-year-old girl in the same woods.
Now, with only snippets of long-buried memories to guide him, he has the chance to uncover both the mystery of the case before him, and that of his own shadowy past.
