Summary: Six medical students; soulful Seon-hwa, arrogant Jung-seok, warmhearted Gi-beom, bookworm Eun-ju, goofy Kyeong-min and sexy Ji-yeong begin the long-anticipated anatomy course. The highly competitive yet close group of friends is presented with a cadaver of a young woman who was once beautiful, with a rose tattoo on her chest.

Yet ever since beginning the lesson, they are all haunted by the same nightmares and hallucinations - a weeping woman and a doctor with a lame leg, whispering death.

One night, Eun-ju is trapped alone in the dissection lab. She screams for her life, but is rescued too late as she lays lifeless and heartless - literally having had the organ surgically removed.

After Ji-yeon dies the same way and other horrible events ensue, Seon-hwa, Jung-seok and Gi-beom are convinced they are next. Everything points to the cadaver: while tracing the woman's past, the students discover that their professor, nicknamed "The Technician'' for his exceptional skills and coldness, is linked to the mystery and Seon-hwa must revisit her own secrets.
