When promoting a new clothing line, Dethklok experiences the brutality of negative body image, dieting, and bulimia.
Metal meets mid-west etiquette when Pickles' brother, Seth, invites Dethklok to his Wisconsin wedding.
In an effort to make friends, Toki goes to Rockaroonie Fantasy Camp - a weekend getaway to rub elbows with rock and roll royalty (but he attends as a camper.) Instead of meeting friends, he is bullied by other campers and has no one to turn to but celebrity counselor, Magnus Hammersmith; ex-Dethklok guitarist with a troubled past. With Toki - the diabetic scaredy cat - out of Mordhaus, Skwisgaar and Murderface act out and over do it with candy and scary movies.
After Murderface is announced as the recipient of this year's Most Brutal Looking Musician Award, he travels to Mexico to get the best and cheapest plastic surgery possible. Meanwhile, the rest of Dethklok deal with the brutality of aging and letting themselves go.
Dethklok returns to the water to record in their new Dethsub but, plagued with the lack of women, carpel tunnel sets in from excessive masturbation. The band regresses to an animal mindset. Pickles and Nathan spend their energy crossing the workplace relationship line and competing for the only woman on the sub: their producer.
As Dethklok hosts the most important dinner of their career, the divvying of album credits, over tagging on social networking sites, and fights over a girl come to head. Can CFO keep their issues in check? Will the record executives forgive them for the past year of mistakes? Or will it be a total, brutal disaster?
While the world awaits the final Dethklok performance, members of the band prepare for their post-Dethklok careers. Pickles starts a winery for the most alcoholic wine ever, Nathan and Swkisgaar look for a brand new sound that doesn't suck, and Toki works with Murderface on his campaign for congressman. Meanwhile, Salacia takes Dethklok's weakness as the opportune time to strike!
