When Homer was trying to get candy out of a machine in the Nuclear Power Plant, Noir Homer came through. He said that the case was going to be like Homer's skull, hard to crack and not much inside. He, along with the other Homers who came through then went around Springfield together, eating, bowling and causing trouble. In order to get them all home safe, Marge opened a beer, causing them all to come rushing to her.
When Ned Flanders appeared, Noir Homer shot his head off, with Ned saying that he forgives him. The Homers found out that they all have to go home to their universes or they will die, so they went to the Power Plant and attempted to recreate the way they got there. Mr. Burns tried to stop them as the device is a way for him to get cheap, undocumented labor. A group of alternate Mr. Burns' then appeared to fight the Homer group, with Noir Homer fighting against another Mr. Burns. The alternate burns stabbed Noir Homer through the heart.
Back at home, Marge was happy to have Noir Homer to herself. However, Noir then turned into Homer Barbera when making out with Marge. Homer Barbera then ran away.
