In the film, a talented but troubled young Baltimore cop is recruited by the FBI to help profile and track down a murderer.

Vertical Entertainment gave the film a limited theatrical release in the United States on April 21, 2023 where it received mixed to positive reviews.

The next morning, Lammark meets with Eleanor for coffee, where he explains he wants her, along with fellow agent Jack McKenzie, to work directly with him as a liaison with the Baltimore police during the investigation.

At the Bureau, McKenzie explains that the apartment was uninhabited, and there is nothing to indicate any of the building staff or residents committed the crime, the explosion was caused by a grenade paired with a deliberate gas leak, and that the rifle used for the shooting is a US Army weapon, over 40 years old.

Lammark, Eleanor, and McKenzie travel to the morgue of the shooting victims where they are interrupted by news that Baltimore police believe they have the shooter surrounded and hurry to the scene.

Returning to the Bureau, Lammark, Eleanor, and McKenzie interview three painters who painted the empty apartment, years prior.

Eleanor explains that in the past she suffered from various mental health issues and addictions, including self-harm, and joined the police as a means of taking her life back.

Through security cameras, the team observes the killer and sees him stash a shirt in a bathroom trash can, which is subsequently emptied by cleaning staff.

Under pressure from the Mayor's office, Lammark engages in a risky strategy of showing security footage from the mall on live television and encouraging members of the public to call with information.

They buy her silence on the true circumstances of Dean's death in exchange for a position at the FBI and posthumous honors for Lammark.

In May 2019, Shailene Woodley joined the cast of the film, then titled Misanthrope, with Damián Szifron directing from a screenplay he co-wrote with Jonathan Wakeham.

The website's consensus reads: "Damián David Szifron's stylish direction and fine performances bolster To Catch a Killer's case, but a derivative script throws this thriller off course.
