Thirty-eight days have passed since the previous season's finale, when Dexter killed his own brother, The Ice Truck Killer, and Rita's incarcerated ex-husband Paul told her about his missing shoe.
Doakes is making it difficult for Dexter to resume his killing ways, but his first opportunity is ruined by something much more unexpected.
Deb returns to work and finds herself under scrutiny from the public, as the freaks of Miami attempt to tap into her newfound celebrity status.
Paul continues to ask for Rita's help, and she begins to look at Dexter through new eyes.
In the meanwhile, the new season opens as treasure hunters make a gruesome discovery on the ocean floor...
Produced by Showtime, Dexter is executive produced by John Goldwyn, Sara Colleton, Scott Buck, Manny Coto, Tim Schlattmann, Wendy West, Jace Richdale and Michael C. Hall.
