Aaron Eckhart And A K-9 Warrior Unleash Mayhem In Muzzle: City of Wolves Trailer

RLJE Films dropped the first trailer for 'Muzzle: City of Wolves', the follow-up to the K-9 cop thriller 'Muzzle' with 'The Dark Knight' alum Aaron Eckhart back in the lead. The movie hits theaters November 14, 2025, and the vibe is very much: ex-cop with a loyal dog, a score to settle, and a city full of people who picked the wrong guy to mess with.

What the trailer teases

Eckhart returns as Jake Rosser, still dealing with the fallout from his past life on the K-9 unit and now laser-focused on the folks who went after his family. He pairs up with a new four-legged partner and wades into a mess of gang violence, corruption, and general bad-guy activity. The footage leans hard into shootouts, chases, and dog-assisted takedowns. If you want sleek, grounded action with a grizzled lead and a K-9 that does not miss, this is that.

Story basics

Here’s the clean version of the setup: Jake is trying to live quietly with his family and his retired K-9, Socks. A ruthless crew shatters that peace, and Jake answers by teaming with a new partner, Argos. The deeper he digs, the more he runs into dirty officials, a drug pipeline, and his own PTSD. So, yes, it’s revenge, but it’s also one of those 'the system is rotten' runs through the criminal underbelly.

"Jake Rosser is haunted by PTSD from his days as a K-9 officer."

The takeaway

'City of Wolves' looks like a lean, 90-minute bruiser with Eckhart in full steely-growl mode, a new K-9 partner named Argos, and a trail that runs from a family-targeting gang straight into a drug ring and dirty halls of power. Trailer’s out now if you want a taste of the mayhem.
