Again, "Dexter" is on the brim of being caught when his ritual is stopped in the middle and his prey gets away. Striving to bring some normalcy back into his shattered life, Dexter figures the answer lies in finding a new serial killer to bring down, but his quest gets thrown off course when his troubled new acquaintance requires his help.

Meanwhile, Batista uncovers a revealing new lead in the Santa Muerta homicides, and Quinn gets a tip about Dexter, but is not sure he can trust his source. "Everything Is Illumenated" airs as Halloween episode on October 31.

Two sneak peeks are released in companion of the preview. One clip shows Debra helping Dexter to move out of the home he used to share with Rita. Debra, who suggests Dexter to move back to his apartment, discovers a sunglasses among the pile which actually belonged to Lumen. In the other clip, Debra plans a stake-out around a lead in the Santa Muerte case and the Chief joins the briefing only to lift the pressure on Debra.
