She gets back home and Frank goes off to a political meeting.
Scarlett is mad at him for leaving her; she also hasn't figured out what you all probably already know, which is that Frank is in the KKK.
At Melanie's, Archie and India and Melanie are very tense.
Scarlett doesn't know why, but they're all upset because the men-folk are out KKK-ing like heroes, and/or like evil terrorists, depending on your perspective (the second one is the right perspective, though).
India and Scarlett have a fight; India blames her for putting herself at risk and causing the attack and leading to men having to do what men do.
Because obviously if women go out by themselves they inevitably provoke attack and it's their fault.
India still hasn't managed to tell Scarlett about the KKK when Rhett shows up, saying he was with Yankees and they told him that they've set a trap for the KKK.
Rhett gets Melanie to tell him where the KKK meets, despite India thinking he's a traitor.
Rhett rides off heroically to save the racist violent vigilante thugs from the consequences of their actions. Hooray.
The women stay put and pretend to be sewing in case they're being spied upon.
Sure enough, Yankees show up.
Melanie starts reading Les Misérables, a famous book about the trials of poor people. Oh, the poor KKK, riding through the night to murder people.
Then they hear Rhett singing and Ashley and Hugh Elsing speaking in a drunken voice.
They all pretend they were drunk and at Belle Watling's house drinking and gambling and paying for prostitutes, effectively fooling the Yankees.
They go, and then they have to tend to Ashley, who was pretending to be drunk but was actually shot.
They'd escaped by sneaking into Belle Watling's for shelter.
Rhett has a key; apparently he does sleep with her.
Belle helped them all out because—like the black people in the story—she loves a society that treats her like dirt.
(In case you hadn't noticed yet, Gone with the Wind loves to believe that people who are treated like dirt adore their oppressors.)
Anyway, Rhett sends Archie off on an errand and it turns out that errand is to bury Frank, who has been killed.
