The SBS mystery-thriller Queen Mantis is heading toward its finale, with the last two episodes set to air this week. The show, which stars Go Hyun-jung as serial killer Jung Yi-shin and Jang Dong-yoon as her detective son Cha Soo-yeol, has kept viewers on edge with its intense storyline and gripping performances. As the copycat killer’s game reaches its peak, fans are eager to see how the story concludes.
Final Episodes Release Details
Queen Mantis episodes 7 and 8 will air on September 26 and 27, 2025, at 9:50 PM KST on SBS. Each episode has a runtime of approximately 70 minutes. Following the broadcast, the episodes will be available for streaming on platforms like Netflix, KOCOWA, and Rakuten Viki in select regions. International viewers should check their local streaming services for availability and subtitles.
What to Expect in the Final Episodes
The previews for episodes 7 and 8 suggest a high-stakes showdown. Jung Yi-shin threatens the police, demanding that her son Soo-yeol be reinstated to the investigation team. The police reluctantly agree, but Officer Na-hui grows suspicious of Yi-shin’s motives, believing she is using Soo-yeol for her own plans rather than helping solve the case.
The funeral of Park Min-jae, who was brutally killed in episode 5, will be shown, with Soo-yeol attending in grief. The copycat killer continues to target Soo-yeol’s family, putting his wife Jung-yeon in danger. As the case escalates, Yi-shin becomes directly involved, ignoring Soo-yeol’s warnings that her actions could cost her life. She insists on moving forward, setting the stage for a dramatic confrontation.
Story Recap So Far
In episodes 5 and 6, Soo-yeol discovered Yi-shin in his home, leading to a tense exchange where Jung-yeon learned the truth about Yi-shin’s past. Soo-yeol continued to struggle with his mother’s legacy, especially after the copycat killer murdered Park Min-jae, a young man who idolized Yi-shin. The investigation revealed that the killer might be Kang Yeon-joong, the child of one of Yi-shin’s past victims, who has since transitioned into a woman.
Soo-yeol’s secret—that he is Yi-shin’s son—was exposed to his team, resulting in his removal from the case. He confided in his wife Jung-yeon, revealing his fears about carrying his mother’s “monstrous blood” and potentially passing it on to their child. This emotional confession left their relationship uncertain as the story moves into the finale.
