Season Four Synopsis

Official US DVD Synopsis:

"The Fourth Season brings not just one, but two new arrivals - a Harrison Morgan and The Trinity Killer! The groundbreaking and critically acclaimed original series by Showtime, starring Golden Globe winner Michael C. Hall, returns on DVD with all 12 thrilling and riveting episodes.

America's favorite serial killer has gone from freewheeling bachelor to responsible husband and doting dad. Maintaining an average-guy facade while satisfying his need to kill has never been easy. But now, with wife and kids in tow, Dexter's got more to lose than ever, as he gets drawn into a deadly game with a killer every bit as dangerous - and conflicted - as he is."
