Dexter continues on the trail of a dangerous new victim, while the traumatised Debra loses control on the job. A high-profile FBI agent arrives in Miami to investigate a newly discovered serial killer, the Bay Harbor Butcher.

Dexter's sudden inability to deceive has him pursuing a slick liar as his next victim, while Rita believes he's concealing a drug problem and forces him into a twelve-step programme where he meets Lila, a seductive new woman.

Rita finds herself threatened by Dexter's sexy new Narcotics Anonymous sponsor Lila, and stressed by a visit from her estranged mother. Dexter tries to throw the dogged, intelligent FBI Agent Lundy off his bloody trail.

Dexter discovers that the man who murdered his mother in front of him as a boy is still alive, and confronts the killer as part of his recovery from addiction - but he also discovers that old impulses die hard.

A new copycat killer openly mimics and claims to be inspired by the Bay Harbor Butcher, driving the annoyed Dexter into the arms of Lila, a development that could spell the end of his relationship with Rita.

Dexter decides that Lila is becoming too attached and that 'recovery' isn't working for him. Debra and Lundy find a clue that points to the Bay Harbor Butcher being right under their noses.

Dexter tries to distance himself from Lila, but discovers she is not willing to let go of their relationship. Lundy's manhunt makes Dexter nervous - but it's Dexter's worst enemy who learns his secret.

Dexter's world comes crumbling down when Doakes tracks him to the scene of his latest kill and reveals a devastating secret about Harry. The Miami Metro PD closes in on the Bay Harbor Butcher.
