My Super Psycho Sweet 16: Part 3

A flashback reveals Charlie Rotter's gruesome killings: he murdered two teenagers for insults and dismembered four others, a spree that only stopped when his six-year-old daughter Skye alerted the police. A later news report suggests Charlie was believed dead in a bus accident en route to prison.

Madison Penrose ignores her father’s warnings and chooses the Roller Dome as the venue for her Sweet 16. She aims to make a splash and boost her popularity, not realizing the danger the night will unleash. The decision sets the stage for a night where past sins resurface.

Skye, now a high school student living with her aunt, faces relentless mockery because of her father’s crimes. She dreams of becoming an artist, but the stigma isolates her from peers. The hostility foreshadows the violence that will spill from the Roller Dome into her life.

Skye meets Brigg Jenner and his friend Derek, and an undeniable chemistry begins to form. Brigg’s interest in Skye contrasts with Madison’s circle’s scheming. The pair’s connection becomes a focal point for the social tension surrounding the party.

After a run-in in the locker room, Skye discovers her locker smeared with red paint and cruel notes. Lilly McFadden privately dislikes Madison and encourages Skye to seek revenge, though Skye remains hesitant. The incident plants seeds for a dangerous plan to crash the party.

Madison distributes party invitations to her friends and deliberately places one in Brigg’s hands to provoke jealousy. The mood at school shifts as gossip spreads about the impending party. Skye’s decision to attend becomes more complicated as Brigg’s involvement deepens.

Derek mentions crashing the party, and Lilly secretly helps by loosening access to the venue. The two reconnect in the basement, strengthening their own bond while Madison’s circle schemes continue. Skye worries that the plan could be dangerous.

Inside the Roller Dome, the party planner is fatally attacked by Charlie Rotter, who has somehow survived the bus crash. Derek uses Charlie’s mask to intimidate Kevin, stirring fear and pandemonium. The crowd’s celebration rapidly dissolves into chaos.

Madison catches Skye laughing with Brigg, and jealousy spikes in her circle. The party atmosphere darkens as suspicions rise and the first signs of real danger appear. Illicit schemes intensify as the night spirals toward catastrophe.

A drunken Lilly overhears Derek’s distress and frees him, while Skye glimpses her father on a balcony, only to discover it is Kevin in disguise. Charlie violently attacks Kevin, confirming the killer is still in control of the night.

Chloe and Olivia plot a prank involving a fire extinguisher, but Charlie grabs the extinguisher and bludgeons Chloe to death. The chaotic mood escalates as the body count climbs. The remaining partygoers scramble for exits as fear takes hold.

Lilly finds Madison’s silver BMW outside the roller rink and carves 'Happy Sweet 16' into the paint, unaware that Charlie is hidden in the car waiting to strike. The chilling discovery foreshadows a deadly turn in the night. Tension tightens as danger looms.

Olivia is found beheaded by Charlie, signaling a full-blown massacre as the party devolves into pandemonium. The killer continues to methodically pick off Madison’s circle. Fear spreads as guests flee in every direction.

In a climactic confrontation, Skye lures Madison away and locks her inside the basement with Charlie, cutting off any chance of escape. The police arrive as Brigg regains consciousness, and Skye escapes in Madison’s car.

Brigg wakes in a hospital bed with Skye nearby in a dreamlike state, implying a final test of trust and fear. A nurse reveals Skye has not been located, and a self-portrait left behind hints that she may still be out there. The closing moment suggests the lines between victim and perpetrator remain blurred.
