Dexter knows it's only a matter of time before Miami Metro discovers the Trinity
Killer's latest handiwork. Therefore, he has to work doubly hard to stay one step
ahead of their investigation. Meanwhile, Debra becomes frustrated when she finds herself
shut out from her own case. She considers bending the rules in the name of justice,
risking her career in the process. LaGuerta and Batista come to regret a major decision,
and realize that by playing by the rules they may have painted themselves into a corner.
And when the friction between Rita and Dexter comes to a head, Dexter gleans relationship
advice from a most unlikely source.
