From the writer of “Cocaine Bear” (2023), Jimmy Warden, comes a wacky genre-melting pot in the form of “Borderline” (2025), a horror comedy thriller directed by Warden, focusing on the stalker and pop star dynamic and pushing that premise to an absolute breaking point.

Borderline (2025) Plot Summary & Movie Synopsis

Who is Paul Duerson?

The movie begins at the end—Paul Duerson (Ray Nicholson) finally marrying his favorite pop star and the love of his life, Sofia (Samara Weaving), before Paul’s voiceover takes us back to the beginning. That would be his first attempt at marrying Sofia. Duerson’s fandom, as it turned out, is quite well known, especially to everyone within Sofia’s vicinity. In Duerson’s imagination, he and Sofia had been together for quite a while, and now asking the question was inevitable.

But this highly active imagination blurred Paul’s reality, whereby he would forget whether he had been play-acting to convince Sofia’s head of security, William (Eric Dane), or whether he had been actually proposing to Sofia. To a certain extent, even William sort of empathized with Duerson, because William had also been lonely after the death of his wife, and Sofia humored him by actively helping him assemble jigsaw puzzles and thus keep him company. Thus, William could never actively exhibit cruelty while ordering Duerson to walk away before calling the police.

That, however, turned out to be William’s mistake, as Duerson doesn’t listen to William and instead threatens to kill himself using his “rajput knife.” As William tries to convince him to give the knife up, Duerson changes tact, calling and essentially proposing to her. William accepted that “proposal “ to keep up appearances and take the knife away, but would instead be stabbed in the gut. Duerson, nonchalant at the impact of the deed, walks into the house and has a right old time in the place, essentially familiarizing himself with the house and feeding further into the obsession of being Sofia’s confidant and lover who knows everything about her, before he calls the police on himself.

How does Paul resume his plan after six months?

Six months later, we find William having rejoined the head of security for Sofia, much to Sofia’s pleasure and to the displeasure of William’s daughter Abby, who wants her father to take up another job that wouldn’t let him be hurt again. On the Sofia side, she is currently dating Trevante Rhodes (Jimmy Fails), a point guard for the Denver Nuggets, and she genuinely seems interested in him. Meanwhile, Duerson instructs his childhood friend JH (Patrick Cox) to fetch a mysterious trunk, and a parcel from the post office, before taking his place as the getaway driver as Duerson and fellow prisoner Penny (Alba Baptista) escape from prison. The plan is to essentially resume Duerson’s dream: “convince” Sofia to marry him and ensure every aspect of the “marriage” goes off without a hitch.

The first step of the plan is to psychologically manipulate William. To that end, JH stands outside William’s house while William is working at Sofia’s mansion. Abby’s babysitter Eleanor (Catherine Lough Haggquist) freaks out and calls the police, and William, who leaves the mansion with Sofia and Rhodes alone, and one guard at the gate. The police officer doesn’t take the complaint seriously but does agree to stay guard downstairs. After practicing dancing for the next day’s audition, the guard goes to investigate his bike and is killed by JH. William, who reaches the apartment almost immediately after, tries to take Abby and Eleanor with him, but JH would be waiting for him in his car and orders him to drive. Before reaching the mansion, JH would stop the car a few miles to the side and order William to walk out of the car before apparently killing him.

How does Sofia kill Penny?

Meanwhile Penny’s job would be to kidnap Pastor Lutzner from his home, fit him in a trunk, put the trunk on the road in front of the mansion to distract the guard, coincidentally at the same time that the power goes out of the house. While the guard is unable to figure out what is occurring, Penny would sneak up behind him to attack. After a furious and hilarious battle, Penny would be successful in killing the guard.

Back at Sofia’s mansion, Sofia and Rhodes’ relationship hits a roadblock because he finds an envelope listing a series of names that Sofia had wanted to be seen and even had wanted to ensure a relationship for a couple of days as part of a PR stunt. This leads to him being dejected and angry at her, surprised at her apparent narcissism, but when the power to her mansion goes off, he takes the candelabra (with each of the candlestick holders shaped like Sofia’s head) to search for the power breaker circuit, finally locating it at the garage. Unfortunately for Sofia, it is at that exact moment that Paul had already sneaked inside.

Sofia, familiar with Paul but also realizing she is stuck with a man suffering in delusion, tries to escape by hitting him with objects around the kitchen. But as she tries to unlock the latch to the large French doors in her house, she notices Rhodes, locked outside, trying desperately to open the door and rescue her, but she would be knocked out by Paul. Paul drags her and imprisons her in her recording studio. He instructs Penny to keep an eye out for her and help her in her wedding dress (contained within the parcel from the post office). It comes as a shock to Sofia, primarily because she realizes that she can’t reason with Paul, and secondarily because she understands he is very serious about this marriage.

It is in sharp contrast to Penny, who, once left alone, admits that she likes Paul quite a bit but doesn’t believe she is quite as gorgeous as Paul had made her out to be. Sofia challenges her statement by asking to bring her makeup bag, and Penny acquiesces, and unknown to Penny, Sofia had attached the bandaid that Paul had put on her cut forehead, to stop the room from being locked. As Sofia sneaks out, she notices someone entering her room and mistakenly knocks out Rhodes with her guitar. As she apologizes to Rhodes, Penny, having returned, attacks her from behind.

Their fighting did pause because Penny suddenly noticed the piano and ordered Sofia to perform a duet with her. Sofia, baffled, chooses to go along with the flow, much to the confusion of Rhodes, who imagines a live performance of the two gorgeous ladies on a black studio stage. Then Penny attacks Sofia because of her flat tone rather than her attempted soprano, and while fighting, Sofia manages to stab her with the heat dial from the barbecue machine and douse her with lighter fluid but refuses to burn her to death. Undeterred, Penny attacks her from behind, and in the scuffle, Sofia pushes her into the recording room and pushes a burning script page in, burning Penny to a crisp.

Meanwhile downstairs, waiting for Penny and Sofia to come decked up for marriage, Paul, having worn his tuxedo after drawing up a bath, and cleaning his rajput knife, tries hard to convince Abby about being a flower girl for the marriage, while also revealing the pastor locked under the trunk. Impatient, he finally walks up to the studio, missing Sofia, who has just escaped from the room and tries to rescue William’s kid. Meanwhile, Paul sees the murdered Penny and then notices Rhodes and imagines him to be Sofia and convinces him (at knife-point) to wear the wedding dress.

Does William survive the night?

JH has pink eye, which, as he states in his story, occurred due to an injury with a sword. But Duerson breaks the mirage, reminding Penny earlier that he had a worm in his eye. Either way, because JH hadn’t worn the eyepatch, he missed a headshot, with the bullet grazing William’s skull, knocking him out for the night.

He wakes up in the morning after being found by Sofia’s PA, who was driving to the mansion. Then, he takes her Porsche and drives up to the mansion, only to find it empty and an invitation to the same church that Duerson had planned to marry Sofia before being caught by the police six months ago. He immediately drives the Porsche to that location, informing the authorities on the way.

Does Paul Duerson marry Sofia?

Well, technically he does, in his mind. As stated, he had been imagining Rhodes as Sofia, and he is so adamant in his vision that he even refuses JH’s emphatic attempt to convince and point out the real Sofia. To Sofia and Abby’s surprise, William joins in walking Sofia to the stage, where, after Paul’s advice to skip the good stuff, Duerson kisses Rhodes. It is remarkable that when asked whether anyone has an objection, Sofia raises her hand. She is moved by Rhodes’ “sacrifice” at that moment and wants to rescue him by taking his place, but even that is shut down by Duerson. As Duerson kisses “Sofia,” he imagines the “consummation” of that event before stabbing the wedding dress-decked Rhodes.

Is Paul Duerson captured by the police?

As Rhodes falls, the Rajput knife embedded in his ribs, William punches Paul. Baffled at the situation, Paul could only look up to find an angry Sofia looking down on him. Paul, imagination and reality blurred, still points out how much he likes Sofia calling his name before Sofia kicks him across the face, knocking him unconscious.

In the commotion, JH, who is hit to no avail by the pastor, holds Abbey with his gun pointed at her neck. As William tries to salvage the situation, JH, confused, tries to ask the master planner of this group (Paul) whether there is a way to get out of this hostage situation. Unfortunately, he doesn’t receive an answer, and he is too foolish to understand whether anything could affect his conscience. Unfortunately, he wouldn’t have time to ruminate about the situation because an injured Rhodes had managed to pull the knife out and slash JH’s neck from behind, killing him and drenching Abbey with blood, much to her shock.

The movie ends with Duerson imagining walking out of the church, married to the love of his life, and finally sitting in a limousine. In reality the limousine is a police vehicle, and he is being taken back to the institute where he had escaped from. Though at one point, as we see him marvel at being in a limousine and instructing them to drop him off at the Hilton, we see him finally breaking down. It could be construed whether his hallucination finally breaks and realization strikes or whether he is happy that his dream has been fulfilled. For the rest, we see Rhodes and Sofia reconnecting again, while William finally promises to his daughter that he will retire from this job and look for employment elsewhere.
