Dear fans of The Walking Dead: You are invited to spend a day on the set of this AMC smash.

The network has released a new, behind-the-scenes promo for season three, which will premiere this fall and take Rick and the survivors to a brand new setting (a prison) and find them interacting with brand new character (Michonne, The Governor).

UPDATE: Get your first look now at Michonne!
