As Lieutenant Joe Leaphorn (Zahn McClarnon) and his team leave the vast, unforgiving deserts of the Navajo Nation for the neon-lit, crime-ridden streets of 1970s Los Angeles, fans are buzzing: Will justice survive the City of Angels’ deadly underbelly?

Dropping on January 15, 2026, the pulse-pounding official trailer explodes with tension, teasing a high-stakes race against time to save a missing Navajo teenage girl. “No matter how many times you ride out to the desert, you won’t sweat away who you are,” Leaphorn warns in a gravelly voiceover, as the footage cuts from serene Southwestern landscapes to gritty urban chaos—gun cocks echoing, shadows lurking, and a desperate hunt unfolding.

The season’s gripping plot centers on the disappearance of a resourceful 16-year-old Navajo girl who fled her boarding school seeking freedom and connection to her roots—only to tumble headfirst into a sinister web of organized crime. Leaphorn, Jim Chee (Kiowa Gordon), and Bernadette Manuelito (Jessica Matten) must venture far beyond their reservation jurisdiction, confronting “demons lurking in the City of Angels” in a relentless pursuit of an obsessive killer determined to “finish the job.” The trailer hints at brutal shootouts, shadowy figures, and moral dilemmas that could shatter everything these officers hold sacred.

Premiering Sunday, February 15, 2026, at 9 p.m. ET/PT on AMC and AMC+, Season 4 ups the ante with eight hour-long episodes—matching the expanded format of Season 3 after the first two seasons’ tighter six-episode runs. Filmed in Santa Fe, New Mexico, during spring and summer 2025 (with Albuquerque standing in for 1970s L.A.), the production captures the stark contrast between sacred Navajo lands and the perilous urban sprawl.

Star and executive producer Zahn McClarnon is making his television directorial debut this season, directing at least one episode. “I’m looking forward to exploring and inhabiting the character of Joe Leaphorn once again in Season 4, and I’m excited to make my directorial debut on a show that means so much to me,” McClarnon said in a statement. The veteran actor—known for Longmire, Fargo, and Westworld—brings raw intensity to the grieving, determined lieutenant facing his toughest case yet.

The cast remains powerhouse: Kiowa Gordon as the sharp, intuitive Jim Chee; Jessica Matten as the fierce Bernadette Manuelito; and Deanna Allison as Emma Leaphorn. New Season 4 additions crank up the danger—Titus Welliver (Bosch) as ruthless crime boss Dominic McNair, who traffics drugs and stolen goods; Franka Potente (Run Lola Run) as the enigmatic Irene Vaggan; Chaske Spencer (Twilight) as charismatic yet lethal recruiter Sonny, preying on vulnerable young Native men in the city; Isabel DeRoy-Olson as the missing teen Billie Tsosie; and Luke Barnett as FBI Agent Toby Shaw.

Executive produced by legends Robert Redford and George R.R. Martin, Dark Winds boasts a flawless 100% Rotten Tomatoes score across its first three seasons—proof of its masterful blend of cultural authenticity, spiritual depth, and edge-of-your-seat crime drama. Adapted from Tony Hillerman’s beloved Leaphorn & Chee novels, the series has become a standout for its respectful portrayal of Navajo life amid 1970s turmoil.

Catch up on Seasons 1-3 via AMC+, the AMC Collection on Netflix, or Acorn TV before the premiere. With AMC already renewing the show for a fifth season ahead of Season 4’s debut, the mysteries are far from over.

As the trailer declares: “Justice has no boundaries.” But in the unforgiving glow of Los Angeles, will Leaphorn and his team emerge unbroken—or will the city’s shadows claim them? Tune in February 15 to find out. This could be Dark Winds‘ most intense, boundary-shattering chapter yet.
