“The Walking Dead” returns on Sunday, October 6th at 9pm, and today AMC has finally unleashed the full official plot rundown – in the wake of last week’s trailer out of SDCC.

In the brand new season…

The Walking Dead is a story that started 10 years ago with one man trying to find his family. That family grew and gradually communities took shape. They fought and survived, thrived and gave birth to a new generation. It is a tale of humankind and there are more stories to tell.

It is now Spring, a few months after the end of Season 9, when our group of survivors dared to cross into Whisperer territory during the harsh winter. The collected communities are still dealing with the after effects of Alpha’s horrific display of power, reluctantly respecting the new borderlines being imposed on them, all while organizing themselves into a militia-style fighting force, preparing for a battle that may be unavoidable.

But the Whisperers are a threat unlike any they have ever faced. Backed by a massive horde of the dead it is seemingly a fight they cannot win. The question of what to do and the fear it breeds will infect the communities and give rise to paranoia, propaganda, secret agendas, and infighting that will test them as individuals and as a society. The very idea of whether civilization can survive in a world filled with the dead hangs in the balance.

Thora Birch joins the series in Season 10 as a Whisperer named Gamma, and today brings our first look at Gamma along with a few other brand new images from the new season.
