'Fifties Professionals' is an action-comedy series that brings together three middle-aged men, portrayed by Shin Ha Kyun, Oh Jung Se, and Heo Sung Tae, whose lives were irreversibly changed by a mission from ten years ago. The narrative unfolds as these seemingly ordinary men, once leaders in their fields, find themselves exiled to the remote island of Yeongseon following a mysterious incident. The series captures their bittersweet and comedic journey to uncover the truth behind that fateful day. Newly released stills showcase a tense confrontation between Jung Ho Myung (Shin Ha Kyun), a National Intelligence Service black ops agent, and Bulgae (Oh Jung Se), a North Korean operative, aboard a passenger ship during a violent rainstorm. This scene is particularly intriguing as it features Bulgae before he lost his memory, raising questions about his mission, which involved disguising himself as a woman. The plot thickens with the introduction of Kang Beom Ryong (Heo Sung Tae), the second-in-command of the Hwasan gang, as all three characters become entangled in a quest to secure evidence of collusion between a high-ranking North Korean official and Han Kyung Wook (Kim Sang Kyung), the first deputy director of the National Intelligence Service. 'Fifties Professionals' is set to premiere on May 22 at 9:50 p.m. KST and will be available for streaming on Viki.
