While trying to uncover why Louis was killed on his boat, Dexter must out-maneuver Isaak, who's after Dexter - and Debra. New leads are brought to light on the Wayne Randall killing spree case by his alluring former accomplice, Hannah McKay, who Dexter discovers has a secret.

Dexter becomes more intrigued by Hannah, while Debra gets to know local crime writer Sal Price, who has dug up some possibly incriminating dirt on Hannah. Quinn gets made an offer he tries to refuse, while Batista is drawn to a new business opportunity. And try as Debra might, she can't stop LaGuerta from upending the Bay Harbor Butcher case...

Dexter is preoccupied with Isaak still on the loose, but an internal struggle within the Koshka Brotherhood could work to Dexter's advantage. And while Miami Metro is on the hunt for a Phantom Arsonist, Dexter goes to great lengths to protect his relationship with Hannah, asking a favor of Debra that causes her to question her loyalty to Dexter.

After capturing a deadly killer, things go awry for Miami Metro, sending Debra into a tailspin. In an effort to help his sister, Dexter enters into a dangerous game of cat and mouse, while the Ukrainian mob continues to seek revenge.

Things heat up as Dexter and Hannah grow closer, and when Sal Price discovers the two are involved, he wants the exclusive story. Sal helps Debra uncover new evidence about Hannah, while Quinn makes questionable choices to protect his girlfriend, Nadia.
