All bets are off of the eight and final season of the acclaimed Showtime drama, "Dexter" and the "Dexter 2015 Wall Calendar" includes a special collectible poster to commemorate the show's eight smash season. As a likeable forensics expert in sunny Miami, Dexter Morgan uses his bland personality to disguise the heart of a true killer - one with a peculiar sense of justice who hunts only other monsters. Golden Globe-winner Michael C. Hall stars as Dexter Morgan. Jennifer Carpenter returns as his adopted sister, Debra, whose loyalites are tested as never before. The series also stars Desmond Harrington, C.S. Lee, Aimee Garcia, David Zayas, Geoff Pierson, and James Remar.
