Plot
Morgan, alone in the woods, starts having visions of Gavin, a dead Savior lieutenant he was intent on killing but could not, who was then unexpectedly killed by Henry. He attacks Gavin, before realizing he is having hallucinations.
Having taken over leadership of the Saviors following Negan's disappearance, Simon leads the Saviors' convoy to the Hilltop, now intent on wiping out any survivors rather than trying to coerce them into submission as Negan wanted. The convoy's traverse is noticed by Hilltop scouts and the community begins preparing for the imminent attack. When the Savior convoy reaches the community at night, Maggie contacts Simon over walkie-talkie, warning him that she will personally execute all of the Savior prisoners that they still hold captive, should he mobilize an attack. Simon says the prisoners are no longer members of the Saviors since they were captured, much to the prisoners' dismay. As they exchange words, Daryl suddenly arrives, riding up on his motorcycle, and starts opening fire at the Saviors with a machine gun, forcing them to start their attack on the Hilltop, and the battle begins in earnest.
Prepared for the attack, the Hilltop soldiers attack the Saviors from highly defensible positions, taking out several of their numbers. In the midst of the chaos, Simon takes Dwight to work their way behind the attackers. Inside the community, Simon spots Tara and begins to hunt her down. However, Dwight, who has secretly sided against the Saviors, shoots Tara in the shoulder with an untainted arrow, saving her from being killed by Simon. Meanwhile, Rick and his other forces charge in from the outside, chasing out the remaining Saviors. Rick reveals to Maggie that he had attempted to kill Negan just before the attack but failed and feels some responsibility for how this attack went.
The next day, the Hilltop community bury their dead and tend to their wounded, unaware that the Saviors had coated their weapons in walker viscera for the attack. Among those injured is Tobin, Carol's former boyfriend from Alexandria. Daryl accuses Tara of trusting Dwight after having seen him as part of Simon's forces and escaping with the other Saviors, but Tara insists Dwight is still loyal to them.
That night, those infected by walker blood, including Tobin, Kevin and Wesley succumb to the infection and turn into walkers, attacking the sleeping residents of the Hilltop. The walkers manage to kill The Kingdom's doctors, Dana and Kurt along with others. The remaining residents react quickly to put down the walkers, with Carol herself stabbing the reanimated Tobin in the head, saving Bertie. The group realizes that the saviors had tainted their weapons with walker blood. Knowing this, infected with walker blood, Alexandria resident Bruce begs for the group to put him down before he turns. Concurrently, Henry approaches the Savior prisoners with a gun, demanding to know which one of them killed his older brother, Benjamin. When none of them respond, Henry unlocks the pen and enters to threaten them directly. However, one of the prisoners, who had also been hit by walker-coated weapons, reanimates and starts attacking them. In the confusion, another Savior, Jared, wrestles the gun from Henry and leads the other Saviors, as well as Gregory, to escape from the Hilltop during the turmoil.
When dawn breaks, Maggie oversees more burials of their friends. They discover the missing Savior prisoners, though a few, led by Alden, offer to stay and help the Hilltop even though they know they will still be treated as prisoners. Additionally, Carol and Morgan go to search for Henry, who appears to have disappeared.
