Since there was no new episode of Dexter on Showtime last night, due to the holiday weekend, the network has released a trailer for the last three episodes of this critically-acclaimed series, which returns with "Goodbye Miami" on Sunday, September 8. This new footage shows Dexter Morgan (Michael C. Hall) revealing to his sister Debra (Jennifer Carpenter) that he plans on moving to Argentina to get a fresh start. We also see scenes with Daniel (Darri Ingolfsson), the serial killer son of Dr. Evelyn Vogel (Charlotte Rampling) who was thought to be dead, but is going on a new killing spree under the name Oliver Saxon. Find out what's in store for viewers as this hit series comes to a close this month.
