Tell Me Something 1999 (South Korea) is South Korea drama premiere on Nov 13, 1999
A series of black garbage bags filled with dismembered body parts begin to show up around the city: in an elevator, on a highway, at the edge of a basketball court, and rendering the victims nearly impossible to identify. The killer's motive is a complete mystery. Leading the investigation is Detective Cho, a burnt-out cop trying to redeem himself with this case. Setting up a special squad dedicated to these gruesome murders, Cho and his partner, the veteran Detective Oh map out the order of the murders, interchanging the parts like pieces in a grotesque puzzle. Mystified by the surgical precision of the dismemberments and finding a medical antiseptic called "Hexamedrin" spread all over the bodies, the detectives start suspecting a doctor or a biologist as the killer.
A break opens up when Cho is led to a beautiful and enigmatic young artist, Su-yeon Chae, whom all the victims have had relations with. But besides this revealing breakthrough, Cho is far from solving the case. Still not having found a motive, Cho is grasping for many clues. As the murders continue, Cho is drawn closer to Su-yeon and begins unraveling her tortured past, leading to new questions and suspects. Cho and Oh subsequently discover that her father, a famous painter, mysteriously disappeared years before. Cho decides to investigate her late college classmate and current colleague Kiyeon, and her friend, Sung-min.
While Cho questions Ki-yeon, the fragile Su-yeon is attacked but manages to escape. After being released from police custody, Ki-yeon disappears, and the next morning Detective Cho is notified of the fourth murder. Under the rainy urban landscape of Korea's capital, another garbage bag is discovered on a highway. This time, the corpse is a head-less Ki-yeon.
