Dethklok faces life without Offdensen, who has passed away as a result of his injuries at the hands of the Metal Masked Assassin. Mordhaus is now a floating fortress and is undergoing heavy renovations to repair the damage from the Revengencers attack, but due to the band's inability to manage their finances they find themselves in a financial crisis. The band plans the most expensive concert in history to herald their return, but run afoul of their record label's president's son, who wishes to get revenge for an incident at the beginning of Dethklok's career, in which Nathan Explosion punched him over a verbal insult. The concert begins as planned, but the CEO's son literally pulls the plug on Dethklok and refuses to let them continue until they renegotiate their contract on terms much more favorable to the label. Just as Nathan prepares to sign the new contract, Charles Offdensen appears, apparently back from the dead, and tells Dethklok that they should continue with the show and that he will take care of the contract. After the band finishes their concert, Offdensen explains that he had himself pronounced dead at the scene (at the end of Season 2), and that there was something he had to do, and that he will tell Dethklok about it when the time is right.
