Viewers who tuned into Prime Video's new six-part spy thriller, Butterfly, have praised the show as "superb".

Based on Arash Amel's BOOM! Studios' graphic novel series, the story follows enigmatic former US spy David Jungan, whose life in South Korea is upended when the consequences of a decision from his past come back to haunt him. 

It's no surprise that viewers have been loving the show so far, given its impressive creative team. At the helm is showrunner Ken Woodruff, whose TV credits include the critically acclaimed shows The Mentalist and Gotham. He co-creates the show alongside award-winning novelist Steph Cha, known for her Juniper Song detective book series. Plus, with Daniel Dae Kim leading the impressive cast, there's no doubt viewers are in for a thrilling ride.

What is Butterfly about?

The "character-driven" spy thriller explores "complex family dynamics within the treacherous world of global espionage". 

The synopsis reads: "The story centres on 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, and he finds himself pursued by Rebecca, a deadly, sociopathic young agent assigned to kill him, and Caddis, the sinister spy organization she works for."
