‘Harry Wild’ Season 5 Trailer Promises More Murder & More Mayhem

Acorn TV knows exactly what its audience wants: clever murders, eccentric suspects, sharp-witted detectives, and at least one person dramatically staring out a rain-soaked window while discussing alibis. Judging by the newly released trailer and key art for Harry Wild Season 5, the streamer is sticking to the formula and frankly, why mess with a good thing?

The fan-favorite Irish mystery thriller returns Monday, June 22, exclusively on Acorn TV, and the new season looks bigger, bolder, and far messier for retired literature professor-turned-investigator Harry Wild. Jane Seymour once again leads the charge as the endlessly entertaining Harriet “Harry” Wild, proving that retirement is apparently just another word for “solving homicide cases while everyone around you struggles to keep up.”

This season’s biggest draw? The long-awaited on-screen reunion between Seymour and Joe Lando, who famously shared television history on Dr. Quinn, Medicine Woman. Somewhere, 1990s television fans collectively gasped the moment Acorn TV dropped that casting announcement.

Lando joins Season 5 as Pierce Kennedy, a brilliant State Pathologist whose arrival instantly shakes up Harry’s orbit. According to the trailer, Pierce isn’t just another procedural side character who pops in to explain blood spatter before disappearing into the background. He’s charming, clever, and carries the kind of chemistry with Harry that practically dares viewers not to speculate about where this relationship might go. Television remains undefeated when it comes to pairing smart people together and pretending audiences won’t notice the sparks flying across crime scenes.

The upcoming season also appears determined to raise the stakes. Harry, Fergus (Rohan Nedd), and Charlie (Kevin Ryan) are pulled into undercover operations, increasingly dangerous investigations, and murders that look darker than anything the series has tackled before. Thankfully, the show still maintains the playful edge that keeps Harry Wild from drowning in grim detective-drama clichés. There’s wit tucked between the bodies and enough personality to separate it from the endless sea of interchangeable crime procedurals cluttering streaming platforms.

Returning cast members Rose O’Neill, Samantha Mumba, Paul Tylak, and Aoife Mulholland round out the ensemble, giving the series the familiar energy longtime viewers have come to expect. The chemistry among the cast remains one of the show’s greatest strengths, largely because everyone seems fully aware they’re participating in a series where intellect and sarcasm are equally useful survival tools.

Behind the scenes, creator and writer David Logan returns alongside writer Jo Spain, with Seymour also serving as executive producer. That consistency matters. Five seasons in, Harry Wild still understands its identity: stylish mysteries, quick humor, and characters who make solving crimes look far more enjoyable than it probably should be.

The newly released key art leans heavily into the show’s polished mystery aesthetic, with Seymour front and center looking entirely too calm for someone constantly surrounded by murder investigations. Then again, Harry Wild has never exactly been the type to panic. Everyone else does that for her.

As streaming services continue pumping out dark, brooding crime dramas where every detective appears emotionally destroyed by Episode 2, Harry Wild remains refreshingly entertaining without sacrificing compelling storytelling. Season 5 looks ready to continue that streak, with sharper cases, higher stakes, and a television reunion decades in the making.

For mystery fans, June 22 suddenly looks very busy.
