As Vox Machina discovers more about a revenge pact Percy made years ago, Keyleth tries to magically connect with the Sun Tree. She senses its pain as well as a dark force deep below the city of Whitestone. Feeling underappreciated, Scanlan volunteers to infiltrate Duke Vedmire's mansion as a distraction while Vox Machina attempts to rescue Percy's sister Cassandra.

Vox Machina has stopped the Briarwoods’ evil ritual, but at a heavy cost. As they flee the Ziggurat to save one of their own, Percy is eager to take revenge on their prisoner, Delilah Briarwood. When Vex implores him to let go of his vengeance, Percy must confront the darkness within himself.

Knowing that the Titanstone Knuckles are in the city of Westruun, Pike and Scanlan come up with a plan to get them from their current owner, Grog's uncle, Kevdak. But Grog, weakened by Craven Edge's curse and haunted by his last encounter with his uncle, questions whether he is strong enough of mind, or body, to confront Kevdak.

In disguise, Raishan visits Vox Machina with a promise of aid. She tells them of a vestige capable of defeating Thordak; the Plate of the Dawnmartyr. The team is divided on trusting the duplicitous dragon, but journeys to the city of Marquet to test if she speaks true.

Merging her soul with a red dragon corpse, Raishan becomes an unkillable, undead monstrosity. She battles Vox Machina in her lair, trying to erase them before they can foil her plans.
