After killing his brother, the Ice Truck Killer, at the end of last season, Dexter now finds himself unable to kill again. He certainly wants to, and in fact still needs to, but he is too unnerved by feelings he can’t quite understand. Drifting from the Code of Harry, Dexter starts making foolish choices as he tries to get back to his old self; with disastrous results. Debra returns to work at Miami Metro PD but shows signs she is not ready to resume duty after her own recent ordeal with the Ice Truck Killer. Meanwhile, Dexter’s biggest secret is about to surface for all the world to see.

The Ice Truck Killer is finally identified, but something about the suspect doesn't sit right with Dexter.

When the suicide of a powerful, high profile woman reveals a strange pattern of murders, Dexter stalks a killer unlike any he’s had to deal with before.

In the season one finale, Dexter follows the clues left for him by the Ice Truck Killer in an effort to rescue his kidnapped loved one, while Rita's ex tries to convince her that Dexter is too dangerous to be around their children.

Rita, Debra and Rudy join Dexter for a weekend away when Dexter finds out that his biological father, whom Dexter thought had died 30 years ago, has just recently passed away and left him his all his belongings.
