During last night's new installment of Low Winter Sun, AMC offered viewers their first look at The Walking Dead Season 4.

And it involves the prison, zombies, a horse - and Michonne fighting for her life.

The clip isn't especially revealing, but it depicts Carl with a gun, racing to save his friend from two Walkers that have infiltrated the walls. We also see Maggie witnessing the commotion and running to assist from the watchtower.

The Walking Dead Season 4 kicks off on Sunday, October 13. Feast your eyes on fresh footage footage from the premiere now:
