A Very Potter Musical tells the story of Harry Potter's return to Hogwarts School of Witchcraft and Wizardry, his participation in the House Cup Championship, the trials and tribulations of adolescence, and the return of the dark wizard Lord Voldemort and the Golden Trio's attempts to destroy the Horcruxes.

[2][3][4][7][8][9] The musical starred Darren Criss as Harry Potter, Joey Richter as Ron Weasley, Bonnie Gruesen as Hermione Granger, Jaime Lyn Beatty as Ginny Weasley, Lauren Lopez as Draco Malfoy, Brian Rosenthal as Quirinus Quirrell and Joe Walker as Lord Voldemort.

[2][3][4][5][8][10] In late June 2009, the group put the entire musical up on YouTube, and it became a viral video that obtained millions of views.

Draco attempts to intimidate Harry by claiming that he will transfer to Pigfarts, a prestigious wizarding academy on Mars presided over by Headmaster Rumbleroar, a talking lion, but Hermione forces him to back off.

Meanwhile, Defense Against The Dark Arts professor Quirinus Quirrell is secretly conspiring to revive the evil wizard Voldemort, who is parasitically attached to the back of his head.

The trio discover that the first round will involve dragons and eavesdrop on Malfoy hinting at an unrealized crush on Hermione.

After returning from a night of drunken escapades, they reminiscence on past events and how they have become good friends from their time spent together ("Different As Can Be (Reprise)").

Harry continues to neglect his preparation for the tournament, and is caught off-guard when he is forced to face a deadly Hungarian Horntail in battle while his competitors fight imaginary dragons.

Quirrell relieves Voldemort of his worries surrounding their master plan as the two weigh the pros and cons of their upcoming physical separation.

At the Yule Ball, the normally-unattractive Hermione shows up with a gorgeous makeover, causing Ron and Malfoy to realize their feelings for her ("Granger Danger").

Harry develops an attraction to Ginny and asks her to dance, leaving Ron to get "drunk" on Butterbeer and fight over Hermione with Malfoy, causing her to lash out at both of them.

Ginny leaves in tears and a flustered Harry attempts to regain his dignity by cutting in with Cho, causing him to get into a fight with Cedric.

Bellatrix Lestrange arrives to welcome back her master and former lover and reveals their plan to use Quirrell as a scapegoat for the murder of Harry.

Ginny tries to make sense of her relationship with Harry, but he explains to her that as long as Voldemort is around, they can't be together because he wants to protect her.

Snape reveals himself as a Death Eater undercover and meets up with Voldemort, who's in a deep depression after his fight with Quirrell.

Malfoy is ready to follow through his part of the deal, but after a speech from Dumbledore he finds himself unable to give him the final blow.

With Malfoy's help, who regretted his choices, Harry and Ron go to Dumbledore's office to destroy the last Horcrux, while Ginny and Hermione try to contact the Order of the Phoenix.

Dumbledore makes Harry return to the world of the living before leaving for Pigfarts riding Rumbleroar, the lion who acts as Headmaster at the Mars school.

While reading Harry Potter and the Goblet of Fire, Nick Lang and a few others attending the University of Michigan discussed the possibility of Draco Malfoy having a crush on Hermione Granger because of him constantly bullying her, and created the concept of a song "Granger Danger", which led to the idea of making a Harry Potter musical.
