Warning: The following contains possible spoilers for AMC's "The Walking Dead."

It's been one year since we last caught up with Rick Grimes and our very merry band of zombie killers in "The Walking Dead." That means season six is finally upon us! I'll give you a moment to do the Happy Dance...

The sixth season of AMC's smash hit show "The Walking Dead" will debut this Sunday with "First Time Again." For a spoiler-free review of the premiere, you can click here.

According to hypable, someone important dies in the very first episode. Wait, what?

That's right, we get a big character death right off the bat to keep audiences on their toes. If you caught HNGN's interview with Josh McDermitt (Eugene), than you know that showrunner Scott M. Gimple is always trying to top himself in an organic way to keep the show fresh. Well, killing off someone at the start of the season certainly accomplishes that.

Without giving away who bites the big one, here's what hypable had to say about the season six premiere:

"The Walking Dead 6×01 uses its extended runtime to tell 2 stories simultaneously. One depicts the fallout from the events of the season 5 finale while the other finds Rick and the team carrying out one of the biggest plans they've ever attempted. To help viewers understand which storyline they're watching, the showrunners tell one of them entirely in black and white.

"Rick's big plan can't be understated: Alexandria needs to free a nearby group of walkers (hundreds of them) from a quarry where they've been trapped, and send them in a directionaway from Alexandria. The walkers are due to break through their quarry confinements any day now and head towards their safe zone, so a plan must go into action soon.

"Watching Rick and the people of Alexandria - including new character Heath - carry out the plan is suspenseful and epic. This is easily one of the largest and most well-organized missions we've seen Grimes try to pull off.

"The question is: Will it all go according to plan?"
