The film follows two girls: outcast Skye Rotter (Lauren McKnight), and the spoiled Madison Penrose (Julianna Guill) who hosts her sweet sixteen at an abandoned roller skating rink, where a masked killer begins murdering the party patrons.
A flashback reveals that Charlie Rotter, the owner of the Roller Dome, murdered two teenagers for insulting him and dismembered four others before his 6-year-old daughter, Skye, called the police, leading to his arrest.
Ten years later, Skye, now a high school student, aspires to become an artist and lives with her aunt, Sarah.
One day at school, Skye runs into Madison's ex-boyfriend, Brigg Jenner and his best friend, Kevin Donaldson.
Brigg arrives at Skye's house and tells her he has to cancel their date because Madison expects him to show up at her party.
Inside the Roller Dome, the party planner, who is 35, makes inappropriate advances towards the underage Madison, who brushes him off.
Kevin returns and tells Madison that Derek crashed her party just as she notices Skye skating and laughing with Brigg, infuriating her.
After Skye leaves devastated, Charlie grabs Kevin by the throat and severely beats him to death, retrieving his mask afterwards.
Meanwhile, Chloe tells Olivia her plan to prank Skye by ambushing her in the bathroom and spraying her with a fire extinguisher.
Outside the Roller Dome, Lilly finds Madison's birthday present, a silver BMW, in the parking lot and carves "Happy Sweet 16" with a key.
While Madison's father gives a heartfelt birthday speech, Olivia goes to use the bathroom and finds Chloe's dead body.
Olivia's headless body knocks over Madison's sushi cake, causing the horrified guests to run outside screaming.
Madison blames Skye for ruining her party and becomes physically confrontational just as Charlie appears, locking the front entrance.
Skye appears to comply, but instead stabs Charlie in the leg and rushes to free Madison, but she struggles with untying the ropes.
Losing patience, Madison continues to blame Skye for the murders and threatens to make her life miserable if she doesn't hurry.
Without warning, Skye repeatedly stabs Brigg to death as he screams in pain, but he suddenly awakens to a nurse calming him down, realizing it was just a nightmare.
After the nurse leaves the room, Brigg turns over and notices a folded piece of paper sitting on a desk next to his bed.
Gentry went on to say he was aware that the film "is clearly in the "slasher genre" where there are rules viewers expect will be followed.
[2] Scott Foy of Dread Central rated it 2.5 stars and wrote: "Too much of My Super Psycho Sweet 16 is just a regurgitating of teen movie clichés with the emphasis more on the romantic triangle and teen bullying side of the plot than the masked psychopath randomly hacking and slashing party patrons".
[3] Airings on MTV are slightly edited; iTunes and DVD releases are uncut, featuring a bit more gore.
Due to several complaints about the DVD just being a burnt copy of the film,[citation needed] Paramount Home Entertainment announced a Blu-ray Combo Pack edition, but no official release date has been set.
