"Red Swan" is about Oh Wan-soo (played by Kim Ha-neul), a former professional golfer-turned-philanthropist who marries the heir to one of South Korea's top conglomerates, Kim Yong-kook (Jung Gyu-woon).

While Wan-soo and Yong-kook might appear to be the perfect couple, he is a serial adulterer who has long been unfaithful to his wife, Disney said in a press release.

But the arrival of a mysterious new bodyguard, Seo Do-yoon (Rain), tests Wan-soo's loyalties.

Disney unveiled the official trailer for "Red Swan," offering a gripping glimpse into a world of intrigue and danger.

The trailer hints at an assassination attempt on Wan-soo. As the clip unfolds, Do-yoon's voiceover suggests the possibility that Wan-soo's attacker may be someone within Yong-kook's own family.

"Red Swan" marks Rain's first series since "Ghost Doctor" in 2022.

Ha-neul, meanwhile, previously starred in K-dramas such as "A Gentleman's Dignity," "18 Again" and "Nothing Uncovered."
