When a simple missing person case turns into a crime scene, Dexter's cabin becomes home base for the search and rescue. Terrible timing for Dexter, who is trying to reunite with his long lost son, Harrison. As Angela and Harrison become acquainted, Dexter struggles to keep his old and new worlds separate.
Once an abused and abandoned child, Dexter is now a successful forensics pathologist... but lurking just beneath his charismatic personality is a terrible truth. Dexter has corralled his innate homicidal urges into a closely guarded second career: He hunts down and brutally murders those vicious criminals who have managed to avoid the clutches of the law. Basing his life on the teachings of his foster father, Dexter only kills people who truly deserve it: he ensures that those who got away with horrible crimes will never hug again.
