A simple spoiler to start with
The spine has Yamato ><

The ones who made up the mercenary force called Akatsuki were advisors of many countries
The Tsuchikage used the Akatsuki to make money
The Godaime Mizukage interferes, saying her country has no knowledge of this since they're isolated
(This is the Yondaime Mizukage's fault... That is, the Godaime reveals that it is possible the Yondaime has been manipulating someone)
Suna planned the Konoha Crash using the Akatsuki (Well, Gaara's father did)
The Hokage is sceptic, questioning whether they should interfere with these advisors (Danzou is silent¹)
The Raikage vents his anger towards the other Kage
Those able to control the Bijuu: Madara, the Shodai Hokage, the Yondaime Mizukage, Killer Bee

Then the neutral power states their opinion
How about making an alliance of the Five Countries?
Then the Hokage, whose country still has its Bijuu, will take supreme command (since there's no hope for the rest). What do you think?
upon hearing that, the Raikage ask "What the hell!?"

And it ends with this　

the Yondaime Mizukage's face is revealed (a gentle man), but (with the Bijuu controlling story) the Tobi = the Yondaime Mizukage things seems to still be okay (since Kisame called him the former Mizukage-sama)

¹ This could also mean that he refuses to explain himself

458 The great debate of the five kage

Gaara: I will talk, listen
Earth: The five kages have changed a lot, if you can be a kage so young. Kazekage, your father was a wonderful leader, but he seems not to have taught you manners. (Ain't that the truth)
Gaara: probably... That's why I am the Kazekage here
Earth: Gwa ha ha ha, cheeky fellow!!
Water: Tsuchikage-sama, do not interrupt. Please go on, Kazekage-sama
Gaara: I'm a former Jinchuuriki. I was abducted by Akatsuki and almost killed when they extracted the bijuu.

Temari, Kankurou are looking in the conversation
Kankurou: What's with the Tsuchikage!
Temari: Be quiet

Gaara: That's why, thinking of the extreme threat posed by Akatsuki, I made many requests for the five kage to collaborate, but I was ignored. ...Apart from the former Hokage. Now that Jinchuuriki have been taken, it is too late to collaborate.
Earth: Huh... The Jinchuuriki of the hidden villages of the five great countries have been taken. What would it show to other countries is they knew. We would be ashamed! It is common sense to keep our secrets. Now that they have been taken, the assistance of other countries cannot be counted on!!

Gaara: Keeping appearances... Honor... That is stupid ancient thinking
Earth: (huh... What a brat...)

2nd part

Water: The fact they have been taken should be a cause of alarm. To control them, we need techniques, knowledge, and time.
Earth: The Jinchuuriki grow with the bijuu. They need to adapt. And even then their control is difficult... Not to say impossible... Isn't it?... Kazekage...
Gaara: ...
Danzou: In the first place, the only people who could ever control bijuus in the true sense were Uchiha Madara and the first Hokage, Hashirama... And the fourth Mizukage, Yagura ...There was also the brother of the Raikage, Killer Bee, but...

Fire and Water minders react.
RAIKAGE BREAKS THE TABLE!! (YEAH! )
Raikage: Enough with all this useless chatter!!
All the minders move in to calm him down
A strike, another strike stopping it. We can see Kankurou's puppet

Mifune: This is a meeting, people. Mind your manners
Danzou: Calm down, Fuu, Rune.
Gaara: You too, Kankurou, Temari.
Water: Aoi (?), Chojiro, no problem...
Earth nods to Aka- and Kurozuchi

Raikage: Konoha! Rock! Sand! Cloud! Akatsuki is made of missing-nins from you villages! And that's not all!! Your predecessor kages included, there are some among you who have made use of Akatsuki before!!
Gaara: Made use...?
Raikage: I cannot trust you all! I did not want to talk to you at all! But I came, and I called you here, to ask your word!!
Gaara: What do you mean, made use of Akatsuki!?
Raikage: They didn't tell you anything, even though you're the Kazekage? Ask the old-timers of your village! You used Akatsuki in previous battles!
Earth: ...

3rd part

Earth: The great countries are all at peace now... We have switched from the armament race to disarmament. With the tension between countries, the risk of battle has diminished. For the countries, the military forces are now a costly burden... But there is still a risk of sudden wars! It is a problem to rely on shinobis without combat experience, you lose battles that way
Gaara: To avoid this risk, one way is groups of mercenaries... That is what Akatsuki was, then?
Earth: It takes times and money to raise good shinobis in our village, but Akatsuki, whose occupation is to always fight, is a team of professionals. But for not much money, they gave superior results!
Raikage: Don't be so defiant, Tsuchikage!
Earth: Huh!
Raikage: The sand used Akatsuki to attack Konoha, that's Orochimaru...! It is unclear whether at that time, he had left Akatsuki or not! And the former Hokage and Kazekage died
Raikage: I would like to be sure nobody schemed all this
Raikage looks at Danzou (perceptive, ain't he?)

Raikage: (...Old racoon...)
Raikage: The most suspicious of all is hidden mist!! You have no diplomatic relations... There are rumors that Akatsuki started there!!
Water: ...

Water: Since we're at that point, I'll say it clearly...
Aoi: Could the fifth (Mizukage) mean that...!
Water: The previous kage... There are suspicions that the fourth mizukage could have been manipulated by someone... It may well have been by Akatsuki... That's why I did not want to talk about it...
Raikage: All of you...!!
Earth: ...!!

4th parth
Earth: Mind your tongue, Raikage! Even though this is a time of disarmament, you are not follwing, and are gathering forces and techniques... Maybe you hired Akatsuki too
Raikage: What!!
Danzou: Before you start bickering, there is something I wanted to say to all of you...
Raikage: What!?
Danzou: The leader of Akatsuki is probably Uchiha Madara

Four others: !?

Earth: That guy surely died long ago...!?
Danzou: We don't know that for sure... but we have pretty clear information
Earth: Was he really such a monster?...

Mifune: From the point of view of a neutral country, I'll say this. The leader of Akatsuki has read how the times were going... Peaceful countries... And has magnified the distrust between countries... Even in the iron country... But this has turned to our good fortune... Did the five kage not gather, for once? Until Akatsuki is destroyed... The hidden villages of the five greatest countries in the world... could form a joint alliance.
Raikage: An alliance!?
Danou: ...Good plan. We need a collaboration equal to the emergency (...going the right way)
Mifune: It is desirable to have a unified command, in order to minimize the confusion
Earth: Then... The problem is, whom do we entrust the authority over the alliance...
Mifune: There is disagreement between you... As a neutral country, our choice would be more respected. I would like to propose who would be the best among the five kage.
Danzou: The ear of Tsunade is now over

Final part
Sakura's tent

Sakura: Naruto...!
Sai: Yes... To protect Sasuke, he got badly hurt... But he couldn't sell Sasuke. And then... He did not tell you, so as not to make you worry
Sakura: ...
Sakura: (Naruto...)
Sai: Now he's gone to ask the Raikage to forgive Sasuke... It's probably hopeless...
Shizune: But why be so reckless? Kakashi is with him
Sai: Kakashi-sensei trusts Naruto. I think that even though it was hopeless, he wanted to create a chance
Shizune looks at sleeping Tsunade
Sai: I was initially assigned to Kakashi's team to replace Sasuke, so that's why I don't understand them too well... ...I don't understand people's feelings too well either

Sai thinks of his talk with Naruto
Naruto: (...I can't even keep my promises...)
Sai: And I don't know what was your promise with Naruto...
Sakura: ...!
Sakura remembers the promise
(Naruto... It's my wish of a lifetime... Please, bring back Sasuke-kun)
Sai: But... That Naruto really likes you... Even me, I can tell that!!
Sakura: ...!!

Sakura's flashback (yay...)
Small Naruto: Sakura-chan Likes Sasuke a lot...
Tears in her eyes
Small Naruto: I know that Sakura-chan is hurting so much, it's painful... I will definitely bring him back home! It's my promise in a lifetime!!
Tears are flowing from her eyes
Small Naruto: ...Sakura-chan! I... will definitely keep my promise. I don't change back on my word. That is my way of the ninja...
Sakura: Wa... ha...
Okay, she's crying

Shizune: Sakura...
Sakura: Uh...
Sai: Naruto is suffering because of Sasuke but... what about you?
Sakura realizing

Back to the meeting
Mifune: Now, only Konoha has a Jinchuuriki... The way he's guided is the key... So how about giving the supreme command of the alliance to the Hokage?

Gaara: ...
Raikage: What!?
Earth: Huh!?

Will the meeting be a carnage...!?
