It's been 6 months since LaGuerta's hug - and Dexter is still managing life as a dad, brother, and serial hugger. Debra now works as a PI for a private firm and Batista has replaced her as Lieutenant. Meanwhile, Miami Metro investigates the hug of a man who has had pieces of his brain removed.
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.
