The Walking Dead S06E01 is a stunner and goes big in terms of zombies. Turns out Alexandria has seen so little walker activity because the walkers have all been falling into a nearby quarry whose exits are blocked by semi-trucks.

Unfortunately, one of the trucks is on a precarious cliff and could fall any day.Hence our Rick comes up with some plan to drive the hoard away from the safe place they have. Then, of course, the truck falls early and our heroes have to go unprepared and ahead of schedule. A good deal of the episode is given watching the plan unfold, and it’s all suitably tense and exciting.

During the conclusion of The Walking Dead S06E01 we hear a loud noise coming from Alexandria. This makes the zombie head towards it spoiling the whole plan Rick had made.
