AMC's Dark Winds season 3 finale, titled Béésh Łį́į́ (Iron Horse), aired on April 27, 2025. The show has carved its spot in the crime thriller category, combining psychological drama with cultural and religious undertones of the 1970s Navajo Nation. It is developed by Graham Roland and adapted from Tony Hillerman's award-winning Leaphorn & Chee novel series.
Dark Winds season 3, which debuted in March 2025, maintains the show's signature tone—dark and reflective, but interspersed with surprising moments of humanity and resiliency. It continues to center on Navajo Tribal Police detectives Joe Leaphorn, Jim Chee, and Bernadette Manuelito as they tackle intricate cases that frequently have roots in the institutional injustices perpetuated against the Indigenous community.
Dark Winds has attracted critical acclaim for its suspenseful storytelling, people-focused narrative, and rich, atmospheric environment, with executive producers such as George R. R. Martin and Robert Redford throwing their support behind it. With Zahn McClarnon as Leaphorn, Kiowa Gordon as Chee, and Jessica Matten as Manuelito, the show is headed by a largely Native American ensemble cast.
As it reaches a taut, tragic finale, Dark Winds season 3 reminds its audience once more that in this world, its victories are bought at a great price, and even tiny flashes of hope are worth a crushing sacrifice.
Based on Hillerman's Dance Hall of the Dead and The Sinister Pig, Dark Winds season 3 is riddled with tragic twists, one of them being Teddi's death. She dies after a violent confrontation with Dr. Reynolds, during which she falls, fatally hitting her head, and is later found dead in his car.
Teddi’s death is marked as a tragic moment of Dark Winds season 3. After uncovering the disturbing truth about Dr. Reynolds, who was responsible for killing a child to protect his career, Teddi becomes a liability that he cannot afford.
Despite knowing the danger he poses, Teddi underestimates Reynolds' capacity for violence. When he shows up at her motel under the pretense of needing her help, Teddi lets her guard down.
This leads to a confrontation as Teddi realizes that she is under threat and tries to call for assistance. However, Reynolds acts first, before she is able to make the call for help.
In the ensuing altercation, Teddi slips and hits her head hard, resulting in an injury that proves to be fatal to her. Although Reynolds did not intend for Teddi to die like this, he does nothing to prevent it. Her death becomes another secret he is eager to hide, and he stashes her body in the trunk of his car before heading out to meet his next victim, George.
Following Teddi’s death, Dr. Reynolds remains focused on tying up all loose ends that could jeopardize him. His next victim is George, the boy whose discovery of an arrowhead derailed Reynolds' ambitions of fame. Believing that eliminating George would protect him from exposure, Reynolds tracks the boy to a train station, where he plans to make his move.
However, Leaphorn and Chee anticipate Reynolds' desperation. After seeing Reynolds at the station, they get onto the same train, prepared for a fight. Suspense increases as Reynolds, hurt but still deadly, gets hold of George.
He blames George for destroying his career and seems ready to kill him at that very moment. However, in a surprising turn, Reynolds does not go through with it.
It may be the gravity of his previous offenses that finally catches up to him, or it may just be that he doesn't want a kid's death on top of Teddi's to ruin his image. Either way, he directs his anger at Leaphorn instead.
The standoff abruptly and conclusively ends when Chee intervenes and fatally shoots Reynolds, rescuing Leaphorn. With Reynolds dead, a considerable danger to the community is removed. However, this comes with an immense loss, particularly for those who knew Teddi.
In Dark Winds season 3, while the storyline with Dr. Reynolds plays out, Tom Spenser goes through a crisis of his own. His narcotics operation has been under mounting scrutiny, with Bern closing in on the truth. Spenser relies on his psychopathic but loyal enforcer, Budge, to shut Bern up for good.
Budge's modus operandi is chilling: he locks Bern in her own vehicle and tries to bury her alive, echoing a murder he committed before.
Yet Budge grossly underestimates Bern's strength. She escapes with the aid of a crowbar and disposes of Budge with Leaphorn's metal feather, made for her sometime before.
With Budge dead, Spenser unknowingly finds himself exposed to danger but carries on as usual. He scoffs at warnings to fold operations, believing he's still above the law. His hubris is a product of part ego and part an existential wound: the drug empire he operates was the brainchild of his ailing wife. Keeping it going is a way of keeping her memory alive.
In the end, Bern, with surprising assistance from Ivan, who was not a willing player in Spenser's business, is able to intercept one of Spenser's shipments. She has Ed Henry and Garza arrested, delivering a huge blow to Spenser's network.
However, Spenser himself is able to escape arrest before he can be taken into custody. Although his empire is diminished, he continues to loom as a threat for the future.
