Yellowstone star's new 6-part spy thriller looks like the ultimate binge-watch

Billed as a "character-driven spy thriller that explores complex family dynamics within the treacherous world of global espionage", the series follows David Jung, an enigmatic, highly unpredictable former US intelligence operative living in South Korea, whose "life is blown to pieces when the consequences of an impossible decision from his past come back to haunt him", according to the synopsis. 

It continues: "He finds himself pursued by Rebecca, a deadly, sociopathic young agent assigned to kill him, and Caddis, the sinister spy organisation she works for."

Daniel Dae Kim, who is known for his roles in Avatar: The Last Airbender, Lost, and Hawaii Five-O, stars as David Jung.

He's joined by Reina Hardesty (The Secret Art of Human Flight), Piper Perabo (Yellowstone, Billions, The Big Leap), and Louis Landau (Rivals).

Meanwhile, recurring cast members include Kim Ji-hoon, Park Hae-soo, Kim Tae-hee, Charles Parnell, Sean Dulake, and Nayoon Kim, with Sung Dong-il and Lee Il-hwa appearing in guest roles.

As for the creative team, Ken Woodruff (The Mentalist, Gotham) serves as showrunner and co-creator for the adaptation alongside acclaimed novelist Steph Cha.

Daniel, who is also an executive producer, described the series as "the realisation of a longtime dream to bring together American and Korean storytellers and create a show that bridges two cultures that I love deeply".  

Sharing his gratitude, the actor added: "I couldn't be happier with the creative team we've assembled, both in front of and behind the camera, and I'm grateful to Ken Woodruff, BOOM! Studios, 3AD, Amazon, and everyone else who helped bring it to life."

All six episodes of Butterfly will arrive on Prime Video on August 13, 2025.
