But someone else was there that day... watching, and now, that someone is ready to exact murderous revenge on prom night.

  • Inside an old abandoned building, four children are playing a game in which they all hide while one of them looks for the others, calling out "the killer is coming!" Young Kim and her two twin siblings, Alex and Robin, walk by and see the children playing. Kim and Alex leave, but Robin lingers, hoping to join the game. But upon entering the building, the four kids gang up on her, chanting "kill!" until Robin has nowhere to go. Backing up into a window, Robin crashes through and falls out of a second floor to her death below. One of the kids, Nick, wants to get help, but Wendy convinces all of them that the best thing to do is tell no one and never tell anyone about what happened. Wendy, Nick, Jude, and Kelly swear to keep quiet. As they leave the building and ride away on their bicycles, an unseen person sees them ride off. Later that evening, Robin's father, Mr. Hammond (Leslie Nielsen) and the police are at the scene. They have surmised that Robin was the victim of a sexual attack by a homicidal maniac. They think they know who is responsible and the cops go off to question a suspect.

    Six years later. The now grown-up Kim (Jamie Lee Curtis) and Alex (Michael Tough) are visiting their sister's grave with their parents. A little later, an unseen person with a creaky voice is telephoning each member of the guilty party one by one telling them, "I'll see you at the prom!" The timid Kelly is upset, while Jude and Wendy think that it's a prank.

    Meanwhile, police detective McBride (George Touliatos) is unsettled because a psycho killer named Leonard Murch has escaped from a local clinic hospital. Murch was a known sex offender who the police suspected was responsible for Robin's death. That night when McBride and his men approached Murch for questioning, he fled and after a car cash, wrecked his car and suffered horrible burns all over his body. Murch has been residing in the asylum for the criminal insane and he just escaped and may be heading back to the town where it happened to look for more victims. When the police discover the dead body of a nurse that Murch took as a hostage during his escape from the hospital, McBride and the asylum psychiatrist Dr. Fairchild believe that Murch may have returned to the town for revenge against everyone.

    In town, it is revealed that Nick is Kim's latest boyfriend. Wendy is Nick's ex-girlfriend, and she is certainly not happy that the new couple are going to their senior prom together. Wendy tries to assure Kim that the relationship will not last by telling her "It's not who you go with. It's who takes you home". Later, the school bully and misfit Lou (David Mucci), is messing with Kim in the cafeteria wearing a mouthless ski mask. Alex steps in to defend his sister, and he holds his own against Lou's two pals until Lou sucker punches him in the back. Brought before the principal, whom is Mr. Hammond, he suspends Lou for fighting. As Lou leaves the school grounds, Wendy tries to talk to him. When Nick and Kim are walking around, Nick tries to tell her about that fateful day, but is he not able to.

    Meanwhile, Wendy makes devious plans to break up Kim and Nick, and she tells Lou that she doesn't want anyone hurt. Lou tells her that he will take care of it. Nearby, Jude is picked up for a ride home by Slick, an outcast student who drives a Chevy van, whom he asks her to the prom and she accepts. In the girls locker room after tennis practice, Wendy finds her school photograph torn from the yearbook and hanging on the front of her locker. When Kim and her friend, Kelly, are alone, they hear a loud noise in the locker room and they see that a mirror has been smashed. After checking around the locker room, the return to see that a fragment of the mirror is gone. Jude and Kelly both find their yearbook photographs inside their lockers, as does Nick.

    That night, Lou picks up Wendy to take her to the prom. Mr. Hammond is the chaperone and Alex is the DJ for the disco music. Everyone is having a good time dancing and listening to the music and watch Kim and Nick do their well-choreographed dance on the dance floor before everyone. McBride secretly arrives at the dance to oversee it and to make sure that nothing bad happens.

    Kelly and her boyfriend, Drew, leave the gymnasium for a part of the school where they begin to make out. Kelly decides that she cannot go any further, and an irate Drew goes elsewhere telling Kelly that he knows "plenty who will". After Drew walks out on Kelly, an unidentified figure donning the ski mask and wearing all-black clothing stealthily approaches the tearful Kelly and kills her by slitting her throat with a mirror shard.

    Jude and Slick decide to sneak out of the festivities in the gym for some intimate time as well. Outside, Jude and Slick are in the back of his van enjoying the privacy. After spending a bit of time outside the van, they hear noises and thinking that someone is nearby spying on them, go back inside the vehicle to smoke some marijuana. After a minute, the back doors open and the masked killer stabs Jude's neck with the mirror shard. The murderer then leaps in after Slick who fights back and pushes the killer out of his van and starts it up to run the killer over. The killer leaps out of the way and grabs onto Slick as he is trying to drive away. After wildly spinning around, the killer jumps free and the van with Slick inside goes over a cliff and explodes.

    The killer returns to the school, now wielding a felling axe and follows Wendy out of the gym to the ladies room where she is putting on makeup. The lights are turned off and the killer attacks her. Wendy gets away and a long chase through the school begins as Wendy tries to outrun her axe-wielding pursuer.

The killer, believing Lou to be Nick-in-waiting, approaches from behind and decapitates Lou, with his head landing on the catwalk and causing the students to scream and flee from the gymnasium. The killer is knocked out when he accidentally hits a fuse box. Kim finds Nick and frees him and tries to help him get out of the building.
