FBI Season 7 Episode 7 Plot Recap & Ending Explained
A Murder at the National Park
FBI Season 7, Episode 7, "Monumental," (which can also be streamed on Paramount+) opens with a park ranger being murdered in cold blood by an unknown assailant.
The victim is later identified as Desiree Cole, a ranger assigned to oversee the Greenwich National Monument (the one commemorating the gay rights movement).
Given that it happened on federal land, it makes it a federal crime, which prompts the FBI to investigate.
Maggie and OA respond to the scene where Desiree's body is covered up and the suspect did not take any of her belongings, meaning that it is a premeditated crime.
Back at the FBI headquarters, Assistant Special Agent in Charge Jubal Valentine returns after an exit scare in FBI Season 7, Episode 5, and he leads the team of analysts in unearthing details about the victim and finding potential suspects.
It turns out that Desiree had a messy breakup with her ex-girlfriend, Drew Ambrie, and her gun is similar to the one that was used to kill the ranger.
Drew Insists She is Not a Killer
Maggie and OA head over to Drew's house to ask her directly if she murdered her ex, but she insists that she is not a killer.
Drew's dad, Phil, arrives, to console her, and he also tells the FBI that her daughter is innocent.
After her alibi checks out and her gun does not match the same one from the crime scene, the team is back to square one.
FBI analysts Elise Taylor and Kelly Moran find out that Desiree was involved in an online spat with an anti-woke commenter named ScrollLord who threatened her with violence.
As a result, ScrollLord becomes a potential suspect, and the analysts pull up his identity and whereabouts. It is revealed that his real name is Brandon Halford and he is currently within the vicinity of the house of the director of Greenwich National Park.
The FBI believes that the director is being targeted so the Alpha Team goes to the location where they discover that Brandon is involved in an ongoing hostage situation.
A Larger Online Conspiracy
After subduing the fake hostage situation and easily arresting Brandon, the FBI brings him in for questioning.
Brandon tells them he believes that the National Park Service has been trafficking children and that an anonymous conspiracy theorist online named "Calvin," who claims to be a high-level FBI official, is aware of the organization's secrets.
Meanwhile, the analysts believe that Brandon is part of a group that has been targeting employees of the Greenwich National Monument, mainly because a security guard was also killed a day before Desiree was shot.
Brandon insists that the truth of it all can be found online, which leads the FBI to uncover Calvin's modus operandi.
It turns out that this person utilizes his millions of followers to do his bidding by letting them decode mysterious drops online.
Stuart and Sidney (who seems to be Tiffany's replacement after Katherine Renee Kane's exit in FBI Season 7) notice that there is an ad on Calvin's homepage that directs them to a podcast called The Path hosted by a charismatic extremist, Duke Ducoyle.
It does not take long for the team to realize that Duke is Calvin because he built his brand by decoding Calvin's drops and he earns money in doing so by luring his followers to buy his merch and even kill innocent people.
So Who Killed Desiree?
Stuart and Sidney loop Special Agent in Charge Isobel Castille about Duke's antics, and they decide to bring him in.
Duke, though, is unfazed by the FBI's investigation, insisting that Calvin is the one to blame for the murders. While Isobel claims that Duke is Calvin, there is still not enough evidence to pin the crime on him unless the suspect who killed Desiree gives him up.
While the team believes that Brandon is the gunman, the results of the ballistics of his gun prove that he is innocent, meaning that they have no suspect (again).
Still, Sidney manages to decode one of Calvin's messages, and the FBI and the NYPD work together to protect the Greenwich National Monument from an imminent attack by online cultists.
During the rally, the Alpha Team eventually captures two assailants, and surprisingly, one of them is Phil Ambrie (aka Drew's father).
It is unveiled that Phil commented "Mission accomplished" on Duke's wall moments right after Desiree's time of death, meaning that he is the one who killed her and the other National Monument employee who turns out to be a former army veteran.
With the help of some convincing from his daughter and the realization that there are no kids who are being trafficked, Phil comes clean to tell the FBI that he and Duke planned the attack on Desiree and the other employee.
After the confession, Phil's friend and a fellow online cultist, Kyle, attacked the feds to derail the investigation, but OA subdued him easily.
Duke is eventually arrested after Isobel points out Phil's confession that he is simply obeying his orders, meaning he is liable for the deaths of the two park employees.
New episodes of FBI Season 7 premiere on CBS every Thursday at 8 p.m. ET as the first show in a three-hour block of FBI programming.
