As a child, Rob, then called Adam, went into the woods near Knocknaree with his two best friends. Only he came out, with blood in his shoes and no memory. As an adult detective in Dublin, he hides this past and takes the case of Katy, found dead at an archaeological dig near those woods, with his partner Cassie Maddox.
What Happens at the End of In the Woods
Rob is charmed by Rosalind, Katy's older sister, and lets her steer him. Cassie realizes Rosalind is a psychopath who got Damien, a young dig worker, to kill Katy. Cassie gets Rosalind to admit it, but the evidence is weak. Damien confesses and goes to trial, while Rosalind, who never touched Katy, looks likely to escape serious punishment.
