The episode starts with Randy and Howard explaining their excitement for the new 6D film of Grave Puncher. Heidi quickly spoils the fun by exclaiming that their parents wouldn't let them go to a midnight movie while they are out, much to the disappointment of Howard. Randy brushes off the disappointment and claims that the NinjaNomicon has the answers for an escape. The Nomicons shows Randy the art of escape, but then tells Randy that it comes at a price, which Randy dismisses out of excitement. Then Randy and Howard makes dummies with MP3 sound effect to trick Heidi and escapes out of the window to the theater while Heidi is studying for her driver's test.
Randy and Howard sneak in to the theater after they found out the tickets were sold out. Randy accidentally knocks over a drink and McSquiddles on the projector, causing a malfunction in which Randy dismisses. Randy and Howard find a seat next to Viceroy and McFist, with Randy being highly uncomfortable being around his worst enemy. Howard forces them to stay, saying there were no more seats. The movie starts, but then the malfunction that Randy accidentally causes earlier causes the Grave Puncher as he confuse the seat for graves, to become real and start attack people. McFist thought it is 6D effect but Viceroy says that it is 7D which the fictional becomes real. While the people are slowly figuring out that this wasn't part of the movie, Randy tries to convince Howard to escape, but Howard refuses although everyone else had escaped from the Grave puncher, telling him he wants to know how it ends. Randy replies that the ending will be his death if he doesn't run.
Randy goes Ninja and engages the Grave Puncher in a battle; however, all his new and improved techniques were no match for the Grave Puncher as his body is like hologram itself. Randy manages to figure out how to fix the problem by destroying the projector. Randy briefly transforms into Ninja Rage, using a new attack, Ninja Tengu Fireball. Howard spills his drink on Randy's head, expressing disappointment at Randy for ruining the only screening time and destroying the only projector that could create 6D effect. Heidi catches them both and tries to report it to her parents, but her parents start taking the blame out on her and Howard starts to say it is a happy ending. Randy, feeling guilt and understanding the Nomicon's lesson, takes the blame on himself and Howard. Heidi is relieved and thanks Randy, mispronouncing his name once more, much to Randy's annoyance.
McFist blames Viceroy at the destroyed theater, but when the school janitor comes by and exclaims that he can't wait to spend his money again to watch it again and again, McFist takes the glory and tells Viceroy to get working on another project, to which Viceroy is annoyed and sick of. Randy and Howard endure one week of being grounded and when they finally get out, they ironically start playing Grave Punchers again online after asking how each other feel.
