Season Finales of Dexter, Homeland to Air on Showtime 12/18

Brace yourself. On Sunday, December 18, two explosive finales will change the course of their seasons to come. In DEXTER's sixth season finale, the Miami Homicide Division is in a race against a lunar eclipse to catch the Doomsday Killer before he commits his final gruesome act.

Will Dexter (Michael C Hall) be able to beat them to it? Meanwhile, Debra (Jennifer Carpenter) struggles with, but finally faces up to, a new emotional reality.

In a special, extended hour-and-a-half finale, HOMELAND finds Carrie (Claire Danes) near-catatonic and confined to bed as events swirl around her. Meanwhile, Brody (Damian Lewis) makes his final preparations for the Vice President's policy summit. The pieces to a deadly puzzle are falling into place, but even as she springs into action, Carrie May be too late to put it all together. When the crisis finally hits, no one-not even Carrie-can foresee the outcome of Abu Nazir's long-awaited attack.

Tune in to SHOWTIME on Sunday, December 18th for the season finales of DEXTER at 9PM ET/PT and HOMELAND at 10p PT/ET.
