The Walking Dead Season 6 (2010)

In the wake of a zombie apocalypse, civilization is reduced to a rubble and the base human instinct of survival is the driving force behind the decisions of everyone left standing. The series follows Rick Grimes, a police officer before the zombie outbreak and a de facto leader after, and his group of survivors as they battle zombies and other survivors in an endless search for resources, a place to call home and a cure. When the structure of society no longer exists, the biggest threat to survival isn't the walking dead seeking to devour their human prey. It's other humans.
