Finn hears a mysterious song while judging a Battle of the Bands.
PlotAt the Tree Fort, Finn is on the ground moping about his Finn sword. After dropping one of his "feel better waffles," he moans that everything's broken, ignoring BMO's attempts in convincing him otherwise.
The scene shifts to Jake on the phone with Princess Bubblegum. He reports the situation to her, and Princess Bubblegum then suggests that they should initiate "Plan C." Jake enters his room pulling out a tuna can containing the briefing for Plan C, only to later ask Princess Bubblegum what the plan is about.
Morning comes, and Finn wakes up continuing his loathing. Music is heard in the background, and Finn takes his sword to hunt down the source of the noise. The noise was actually Susan Strong's song, and Finn appears to be delighted by the performance. When her song ends, Jake helps with Finn's confusion by telling him it's a battle of the bands. Bonnibel surprises Finn by making him the judge, adding to his enjoyment. She then goes on to introduce the battle of the bands to the audience, and then cueing MC Neptr and Flame P to perform their song. The duo continue to rap, and once finished they announce their band merchandise, to which Ice King feels they are trying to bribe Finn with.
Princess Bubblegum introduces the next contestant, Marceline. Marceline begins to sing her love song, only to lose her pick half-way through. Finn feels that the winner is Marcy, only to see Marceline distraught about losing her pick. A strange song piques Finn interests, and he excuses himself while the Candy People look for Marceline's pick.
Finn goes behind the stage, catching Jake singing to Lady Rainicorn, which then upsets Jake as Finn is supposed to be the judge. Finn ignores their questions as he continues looking for the source of the tune. Jake and Lady Rainicorn tag along with Finn as he searches
The scene goes back to the upset audience, infuriated due to the postponement of Marceline's song. Ice King attempts to control the crowd, then letting loose his penguins to make peace but they only makes things more violent. Princess Bubblegum finds Marceline's pick in Mr. Cupcake's icing, and Marceline continues with her song. Once finished, she shows resentment after noticing Finn's absence.
The scene goes back to the battle of the bands. The crowd is still rioting, and Ice King seizes this opportunity to preform his song, only to be shut-down by Marceline and Princess Bubblegum.
The Music Hole reveals that it is envious of Finn's ability to fully exist in the presence of everyone. Finn feels lucky that he is fortunate to have possession of this ability. He then announces the winner of the Battle of the Bands, presenting it with a potato chip bag crown. They begin to perform a duet and while singing, the Finn in the Finn Sword appears and nods his head rhythmically while listening. Finn throws the crown into the chasm of Hole's mouth, ending the episode.
