Bree is the wild, hot, natural big breasted single blonde who arrives with her best friends Jenna and Chelsea and several other students, as she accompanies Trent Sutton to his parents' summer home in Crystal Lake for a party-filled weekend in 2008. Her goal for the weekend is to become Trent's girlfriend despite her best friend Jenna being in that role. Reaching the Sutton's summer house, she is seen wearing white pants and a green tank top, complimenting her large rack, and she begins to record her friends having a good time when they are shotgunning a beer can. After Trent yells at them for making a mess, Chelsea whispers into her ear about Bree wanting to sleep with Trent and Bree smiles and laughs about her sexual desires. Sometime later Bree has changed into a tight blue top and short Jean shorts that further compliment her body. Bree then records Chewie and Lawrence munching down. Later, she sees Jenna inviting Clay into the house, says "this'll be interesting", knowing Trent isn't going to like it, gives a mischievous smirk, grabs a beer and offers it to Clay but Trent sees Clay and tells him he needs to leave. After a brief argument, Jenna leaves with Clay, Bree then seductively offers the beer to Trent, who accepts. After their other friends had gone elsewhere, Bree then teams with Trent and plays and loses several games against Chewie and Lawrence, causing both to become a little drunk and flirty. During this time Bree attempts to get Trent interested in her.
As night begins to fall, Bree gets a bottle of champagne and drinks it while dancing in front of Lawrence and Chewie. Lawrence goads Chewie into flirting with Bree by trying to impress her by drinking a flaming shot. Bree, knowing that Trent isn't paying attention and that her friend Chewie has a crush on her, moves to Chewie. Allowing Chewie to attempt to seduce her by drinking a flaming drink, she instructs him by telling him to "bring it to your lips. Blow, then suck." When Chewie tells her that she's good she just smiles. When Chewie burns his lips when he drinks, he breaks a chair which causes Trent to get very angry with him and sends him to the tool shed to they tools to fix it. Bree, knowing that Trent wanted to sleep with Jenna uses this incident for her to steal him from Jenna. Bree walks up to Trent and tugs on his outer shirt and tells Trent to "forget about it. He'll fix it," and tells him that she wants to go finish the champagne in private. Trent, who, at first; was reluctant to cheat on Jenna, accepts Bree's offer.
After heading upstairs, Trent and Bree start making out, before the latter attempts to remove both their clothes. Shortly after, they begin having sex which Bree begins to record. Trent jokingly says that the video better not end up on the internet, and constantly compliments her large breasts. During this time, Jenna and Clay return to the house to warn the others about Jason. While Clay phones the police, Jenna heads upstairs and attempts to tell Bree and Trent, but the door is locked and they assume Jenna is simply messing with them. Continuing with their copulation, they are unaware of Jason watching them through the window, glaring through his mask. Eventually, they climax, and relax onto the bed. They don't get long to enjoy the moment however.
A minute later, the power goes out (presumably Jason's doing), and Bree and Trent get dressed, him wearing the clothes she stripped off him and Bree decides to wear nothing but her underwear and one of his dress shirts. As they come down Bree gives Jenna the look of satisfaction as they are told by Jenna and Clay Miller (who Trent gets in brief fight with) about a killer being on the loose.
When Lawrence goes outside to get Chewie, and is left screaming for help after being injured by Jason, Bree, despite moments earlier being full of confidence after having sex, loses all composure and goes into hysterics, curling up and crying in a corner. Managing to calm down after a little bit, Bree goes upstairs looking for Trent, and wanders into the bathroom. Thinking someone else is in the room, Bree looks around and, after pulling back the shower curtain, is grabbed from behind and gagged by Jason, who had snuck in through the open window. Lifted off the floor, Bree tries to plead with Jason despite being muffled and sees what Jason plans on doing to her. Bree is then thrown onto a rack of antlers which cause her to let out a scream as her heart and lungs are penetrated, resulting in her death. A few minutes after the event, Bree's body falls off the antlers, the noise startling Trent into accidentally shooting her corpse several times. Jason later hurls Bree's blood-soaked body out of a window and onto Officer Bracke's car when Trent attempts using it to escape. This was probably used to frighten Trent the most, as Jason had seen them together not long before.
