Totally Killer

As the moon casts its silvery glow over Vernon on All Hallows' Eve, 1987, a dark and sinister presence lurks in the shadows, claiming the lives of three unsuspecting teenagers: Tiffany Clark, Marisa Song, and Heather Hernandez. Each victim met their demise at the hands of the Sweet 16 Killer, their bodies bearing the gruesome mark of 16 stab wounds inflicted on the night of their 16th birthdays.

Fast-forward to the present day, where Jamie Hughes (Jamie) is celebrating Halloween with her friend Amelia at a concert, while her mother Pam tends to trick-or-treaters back home. Little do they know that Pam's past is about to come crashing down around them. As Pam hands out candy, she becomes the target of the killer's wrath, her life brutally cut short by the very same blade that had claimed those three innocent lives.

As Jamie grapples with the grief of losing her mother, she turns to Amelia and helps her put the finishing touches on a time machine they've been working on for a school project. It's then that they're approached by Chris Dubasage, a curious reporter who shares a chilling revelation: Pam had received a menacing note from the killer, which she kept hidden away - "You're next, one day." The words send shivers down Jamie's spine as she realizes her mother was marked for death.

That night, Jamie finds herself being stalked by the killer and is forced to take refuge in the time machine. As she activates the device, she finds herself transported back to 1987, where she discovers that Pam and her friends were reviled by everyone in town due to their bullying ways. With this knowledge, Jamie sees an opportunity to change the course of events and prevent her mother's murder.

Donning a disguise as an exchange student from Canada, Jamie infiltrates the social circle of Pam and her friends, including Amelia's mother Lauren and Doug, the school's principal. Though she's able to gain their trust, her attempts to intervene in Tiffany's murder ultimately prove futile. Using her newfound understanding of Pam's past to forge a bond with her, Jamie convinces the group to leave town for the weekend - only for them to end up at the very cabin where Marisa met her untimely demise.

As Jamie works to protect Marisa from the killer's wrath, Heather becomes the next victim, forever altering the timeline. The consequences of Jamie's actions are far-reaching, and she must now navigate a complex web of cause and effect as she strives to prevent further tragedy and alter the fate that has been set in motion.

As the witching hour struck on Halloween night, Lauren worked tirelessly to convert a beloved amusement park attraction into a makeshift time portal for Jamie's perilous journey forward. Meanwhile, in the present day, Chris lent his expertise to Amelia as they scrambled to repair their own time machine, only to discover that the fabric of reality was unraveling before their very eyes. The group, however, remained blissfully unaware of the impending doom as they expertly manipulated the Sweet 16 Killer into a haunted house trap, where he met his untimely demise at the hands of Kara (the town sheriff) and her trusty scythe.

As the truth began to unravel like a thread pulled from a worn sweater, Doug's sinister intentions were revealed. Consumed by a burning desire for revenge against the group that had inadvertently contributed to the tragic death of his girlfriend Trish, Doug emerged as the primary killer. But there was a twist - Marisa's shocking confession exposed that she, Tiffany, and Heather had collectively enabled Trish's fatal mistake on a fateful night, while Pam curiously remained absent from the scene.

As Jamie puzzled over Pam's inexplicable receipt of the ominous note, a second killer emerged to slash Marisa's throat. The chase was on as Jamie faced off against this new menace, who mercilessly claimed Chris' father along the way. The two adversaries confronted each other in the newly activated time machine, only to reveal that Doug had been the original killer all along. However, it transpired that Chris from the present had also committed a heinous crime - murdering Pam and fabricating the note to create sensational content for his podcast.

The stage was set for an epic showdown between Jamie and her doppelganger as they clashed in a battle of wits and strength. In the end, Jamie triumphed by sending Chris into the spinning machine's vortex, where he met his untimely demise. Upon returning to the present day, Jamie discovered that Pam remained alive, but the timeline had been altered to such an extent that her parents' union occurred earlier than previously thought. This unexpected twist resulted in Jamie now having an older brother named Jamie, and she was henceforth known as Colette - a name that resonated with her newfound sense of identity.
