STAGE TUBE: Sneak Peek - Season Finale of Showtime's DEXTER Airing 12/18

The sixth season of Showtime's DEXTER comes to end this Sunday, December 18th at 9/8c. On the finale, Dexter and Homicide race against a lunar eclipse to catch the Doomsday Killers before their final gruesome act, while Debra struggles with a new emotional reality.

The explosively popular DEXTER returned with a vengeance for a sixth season of startling suspense and spense and unexpected twists. Since last season's shocking and heartbreaking conclusion, mild mannered criminologist-cum-grisly serial killer Dexter Morgan has come to terms with who he is. But his existence is shattered when he crosses paths with an enemy unlike any he's faced before. A delusional religious zealot with unflinching convictions, this new adversary soon draws Dexter into a dangerous game that could well end in disaster.

Dexter Morgan, Miami Metro Police Department blood spatter analyst, leads a double life. When he's not helping the homicide division solve murders, he satisfies his dark desires by hunting and killing bad guys who slip through the justice system, all the while following a strict code established for him by his father.
