We are introduced to Salem, her subordinates, and the eerie landscape in which she lives - a landscape that spawns new Grimm from pools of black ooze.

Meanwhile, Ruby, Nora, Jaune and Ren are travelling through Anima by foot, fighting monsters and debating their team name as they go.

Ren and Nora's past is revealed through a flashback: years ago, Kuroyuri is attacked by Grimm, led by a Nuckelavee, and Ren's parents are killed. Ren's Semblance activates when he sees Nora in danger, which calms him down and hides their presence from the Grimm. In the present, Ren and Nora realize that the Nuckelavee is headed towards Ruby, Jaune, and Qrow.

Professor Lionheart's method of passing information to Salem is revealed and Weiss' transport runs afoul of the Grimm. Meanwhile, Adam and Hazel meet with Sienna Khan, who is extremely angry with Adam's attack on Beacon Academy.

Ruby and company meet with Lionheart, who is less than thrilled to see that not only is everyone armed but there are more people than he thought.

The fight with Salem's group gets more intense as Weiss is injured, Hazel goes into a furious rage, and Cinder enters the vault.

The fight for Haven continues, but now it's time for our heroes to turn the tides, especially now that a long lost ally has returned with an army at her back.

As the battle for Haven reaches its conclusion on the surface, Yang confronts her mother at the relic vault.

Heroes and villains alike are confronted with troubling revelations.

A Leviathan has emerged from the ocean depths and now threatens to destroy the city of Argus. With Cordo's Colossus incapacitated, the Atlas Base has little they can do to protect the people.

Jaune, Ren, and Yang's pursuit of a mysterious new Grimm results in unexpected complications. Ruby, Weiss, and Blake find a new place to lay low. Cinder receives an ultimatum.

It's time.

It's all out war in Atlas. Our heroes face an impossible problem. Where do they go from here?

The clock is ticking on Jaune, Ren, and Yang's rescue mission. The Ace-Ops hold the line against against Salem's forces.
