Well if we go with the pictures as well
Chapter 1: Georgia's First City
They first go into the city most likely meet another group or residence of Georgia.
Chapter 2: Down by the River
Most likely Lee and the group will help out in this new place and new group. Trying to put their past behind them.
Chapter 3: Support Group
The girl with the axe will appear.
Chapter 4: Bedside Manor
The picture is a hospital symbol so most likely the girl who you meet will tell you about that place and judging from the video in the trailer its not the best place to go while sick.
Chapter 5: Georgia's Last City
Lee's group confront Georgia's group and shit goes downhill fast, Lee's group vs. the new group.
Chapter 6: For Whom The Bell Tolls
The bells are rings for Lee's group death, they go to the church, and i sense this is where we lose someone.
Chapter 7: The Morning After
After loosing someone or multiple people, they long for morning and a brighter day.
Chapter 8: Penultimate
Judging from the picture it seems that they are overrun by zombies. Most likely will have to escape the horde below in Georgia and possibly something will happen.
