Dethklok is asked to host the American Pornography Awards, but Nathan's new controlling girlfriend puts a damper on the situation for the entire band.

The guys pull pranks and go on vacation to celebrate the release of their album, but Nathan senses that something is not right with their latest release. Meanwhile, Skwisgaar and Toki plot revenge on Murderface for his pranks.

The band’s new female producer sends them on a vacation to help write songs for the new album. The getaway proves anything but relaxing, however, when they end up in a brutal country and are sold into sex slavery.

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?

Dethklok is notified of a looming secret that has been around for hundreds of years: the secret of the Metalocalypse. Before they can contemplate what this means, however, Nathan must give a eulogy and do the most brutal thing he has ever done: get in touch with his emotions.
