Everyone freaks out when an entire city in Colorado gets hacked. Gerald faces ruin if his complete history of internet activity becomes public. Member Berries are afraid for their lives and Cartman starts to realize the future is in jeopardy.
In the aftermath of Gerald Broflovski and his Internet troll friend Dildo Schwaggins' successful trolling attempt on Denmark, Schwaggins brings his team over to the Broflovskis' house to celebrate. However, despite having become obsessed with trolling, Gerald is annoyed that the trolls want their relationship with him to continue and grow, causing him to angrily rebuff Schwaggins' repeated attempts to build a real friendship. Heidi Turner and Cartman show Kyle a bulletin board in Heidi's room, where she deduced through emoji analysis that Skankhunt42 was actually a parent of one of the students, although she never found out his identity before she was forced to go offline. Using Heidi's methods, the Danes activate their troll identification website and target one of the troll team's members in the city of Fort Collins, Colorado, publicizing all of its citizens' Internet histories in the process. As the city collapses from the chaos, the troll from Fort Collins is burned alive by the father of one of his victims.
When Gerald discovers that the Danes are close to finding him out, he panics and begs Schwaggins for help, but Schwaggins rejects Gerald for spurning his friendship. When Cartman visits Kyle to try to get him to apologize for supposedly offending Heidi for not being funny, Kyle openly suggests that he would use the Danish website to reveal Cartman's bigoted past and send the information to Heidi. Cartman lies to Heidi about his past, but despite her reassurances, he worries that she will eventually find out.
Randy and Mr. Garrison discover that they cannot kill off the member berries, which are using their nostalgia-inducing abilities to influence the public to vote for Garrison over Hillary Clinton. Clinton's aides are also concerned about the possible release of her Internet activities due to the Danish website, and they suggest that only Skankhunt42 can help her. Randy convinces Garrison to make one final speech "from the heart" to convince his followers to support Clinton. However, the member berries have become intelligent themselves and they attempt to counter Garrison's sabotage by infesting his running mate Caitlyn Jenner.
