Climax (Korean: 클라이맥스) is an ongoing South Korean political survival noir television series directed by Lee Ji-won, who also co-wrote the screenplay with Shin Ye-seul. Starring Ju Ji-hoon, Ha Ji-won, Nana, Oh Jung-se, and Cha Joo-young, the series follows the ascent of prosecutor Bang Tae-seop as he navigates the cutthroat hierarchy of South Korea's power cartel.

The series premiered on ENA on March 16, 2026, and airs every Monday and Tuesday at 22:00 (KST). It is available for streaming on Genie TV in South Korea and, internationally, via Disney+, Rakuten Viki, and Viu.

Synopsis

Climax unfolds against the backdrop of South Korea's powerful conglomerates and entertainment industry, following a couple driven by boundless ambition who'll stop at nothing – including betraying each other – to reach the pinnacle of success.

Cast and characters

Main

A political rising star and feared prosecutor in Seoam District's office. From a poor background, he worked tirelessly to become a prosecutor, only to find the office was corrupt, prioritizing money and power. So he partnered with top star Chu Sang-ah to climb the ranks.
South Korea's top actress. Despite constant scandals surrounding her, her biggest fear is losing herself. She experienced a glamorous period, captivating audiences with her charm and aura, until announcing her marriage to Tae-seop, a prosecutor, in a sudden move that garnered significant attention. Although their marriage sparked rumors, a stronger, more persistent desire drove them. Her standing began to slip as her films flopped and a decade-old murder case regained public attention.
A significant force in altering the cartel's power structure. Her life changed following her mother's death; she was accused of murdering her father and met Tae-seop, the prosecutor handling the case. Upon release from prison, she led a quiet life until reconnecting with Tae-seop, who recognized her intelligence and resourcefulness and recruited her as an intelligence agent.
The eldest son of WR Group and the executive director of WR Construction. He seems elite with impressive lineage, but as he speaks, his true nature's revealed. His father remarried Yang-mi six years ago because of the hotel business. To push her out of the WR heir position, he teamed up with Bang Tae-seop, who had the same aim.
The second wife of WR Group and president of WR Hotels & Entertainment. She navigates both the power structure and South Korea's entertainment industry, with connections in each sphere. Just as everything's falling into place and her goal's within grasp, an unexpected event throws everything off balance.
