It all starts beneath a treadmill with a suspicious stain that definitely does not belong there. Yonggeun Fitness is one of the most popular personal training gyms in Seongwang-gu District, and its night class in particular is so sought after that male members compete fiercely to get in. When the building’s owner, Seon Bin, discovers a strange residue left behind after one of these late night sessions, he begins to investigate what really goes on after hours in Seongwang-gu. What he uncovers is far from ordinary training. The so called night class turns out to be a secret hotspot where workouts are merely a cover for something far more indecent. Furious that such shameless behavior is happening under his roof, Seon Bin vows to put an end to it no matter what it takes. (Source: Lezhin US)
