Friday The 13th: The Final Chapter
Tommy, his sister Trish and thier mother, have been living in a Cabin on Crystal Lake after Mrs. Jarvis got divorced. There are a group of teenagers who are vactioning in a nearby cabin, and Tommy and Trish befriend them. They meet another teenager named Rob Dier, who is visiting Crystal Lake to kill Jason Voorhees, who's sister Sandra (a character from Friday The 13th: Part II). Tommy and Rob befirend eachother and Tommy shows off his skills at making hommade masks to him.

Later, during Jason's latest murder spree, Mrs. Jarvis is killed. After Rob is murdered by Jason, Jason gives chase to Trish. Trish and Jason fight eachother, so that Tommy can make a run for it. Tommy shaves his head bald to look like Jason as a young boy. Jason is momentarily distracted, and Trish ends up knocking Jason's mask off, and he drops his machete. Tommy makes a go for the machete and hacks into Jason's head and when Jason show's signs of life, Tommy angrily hacks into Jason until Jason finally died.

The next morning, Trish wakes up at a hospital. She asks to see Tommy. When Tommy walks in, they share a hug but Tommy was clearly disturbed by what happened.

Friday the 13th: A New Begining
Years after killing Jason, Tommy has shifted to various mental institutions. Tommy arrives in a secluded house for troubled teens, in the woods, called the Pinhurst Halfway House, run by Dr. Matt Letter. At the house, a socially awkward teenager named Joey, is killed by a violent tempared teenager named Vic. Vic is arrested, and a medic named Roy Burns seems espically saddened by the murder.

Meanwhile, Tommy befriends a kid named, Reggie, who's grandfather works as a cook at the camp, and a girl named Pam. In the wake of Joey's death, a new masked killer, dressed as Jason begins murdering residents of the Halfway House and placeing them under Tommy's floors.

Tommy eventually confronts the killer, but passes out from blood loss when the killer slashes him across the chest. Reggie and Pam fight the killer but he quickly gains the upper hand. Tommy musters enough strength to get the killer's machete and hack his hand, causing him to fall on a bed of nials. The fall knocks off the killer's mask, revealing the killer is Roy Burns.

It turns out Joey was Roy's son, and Roy was a naturally quiet loner, and that the death of his son drove Roy insane, like Pamela Voorhees before him. Even thought the real Jason wasn't ressurected, Roy's murder spree did re-awaken Tommy's fear of Jason likely leading to the events of the next film.

Friday the 13th: Jason Lives
Some time after Roy's murder spree, Tommy becomes convinced Jason will come back to life. Tommy heads to Crystal Lake, now renamed Forest Green, with his friend Hawes go to the graveyard where Jason was buried. Upon digging out Jason's grave, Tommy angrily stabs Jason's corpse with a metal rod, attracting lightening. This bring's Jason back to life in a new undead form. Jason kills Hawes, and, with his greatest fear being realized, Tommy flees.

Tommy goes to the police station but naturally, the sheriff, Garris doesn't believe him. The next day, Garris has Tommy escorted out of Forest Green, while Jason begins his new killing spree. Tommy is determined to prove he's right by going back to the graveyard and finding the grave filled up by the caretaker, who was afriad of getting in trouble. Meanwhile, Garris and his men start investigating Jason's murders and believe Tommy to be behind it. Ironically, Tommy befriends Garris's daughter Meg, who believes Tommy and is trying to help him. The two develop and crush on eachother, and later Meg tries to sneak Tommy into the camp to kill Jason, but they are stopped by a road block.

When Tommy and Meg are taken into coustody, Tommy is kept in a cell when Garris gets a call that more bodies have been found in Crystal Lake. Garris and his men go to investigate, but he has one of his deputies look after Meg and Tommy. Tommy and Meg trick the gaurd by kissing, getting the gaurd to angrily go into the cell and Meg takes his gun. She forces the deputy to let Tommy out and to get into the cell, locking him in.

As Jason massacres the police officers at the camp, Tommy sets up a trap for Jason, by using an ancor, a chair taking a motor boat a reasonable distance from the camp, and a ring of gasoline in the water. The chidren attending the camp hide in a cabin. Garris himself is killed when Jason was trying to attack his daughter. Tommy calls out Jason's name. Jason remembers Tommy  and wads into the water. Tommy ignites the gasoline, but Jason emerges by the boat and the two fight, but Tommy manages to wrap a chain around Jason's neck, but Jason succeeds in dragging Tommy underwater. Meg heads out to rescue Tommy, and is attacked by Jason underwater. Meg uses the motor boats propeller to saw-up Jason's neck. Meg manages to take Tommy back to shore and revive him with CPR. The film ends showing that Jason is alive but powerless to move.
