The world at large believes Dexter Morgan died in a tragic boating accident, and in a way the world at large isn't wrong. Far from the life he knew, living under a false name in the small town of Iron Lake, N.Y., he's successfully tamped down his Dark Passenger for nearly 10 years. With a normal job and a girlfriend who's chief of police, it seems he's got life under control -- until his son shows up and turns his world upside down. Rattled, Dexter yields to his homicidal urges and soon finds himself on a collision course with a very dangerous local.
