During the Sunday, August 25 episode of Low Winter Sun, AMC aired a sneak peek of The Walking Dead Season 4. The sneak peek consisted of a brief clip, which focused on Michonne struggling with a couple of walkers. Here's a detailed description of what was shown below.
The sneak peek scene opens with a shot of Michonne on a horse, riding outside the prison. As Michonne approaches the prison gates, Carl runs out and using a pulley system opens an outer door to the prison gates. After Michonne rides inside the first gate, a couple of walkers follow her inside.
Michonne mutters, “Oh, boy,” before jumping down off her horse to deal with the walkers. Michonne is struggling with two of the walkers, while Carl is watching from inside the second prison gate. Maggie hears the commotion and comes running out from inside the prison watchtower. As Michonne continues to struggle with the walkers, Carl picks up a gun and starts to run to help. The scene ends with Michonne still struggling with two walkers.
The Walking Dead Season 4 premieres on Sunday, October 13 on AMC.
