When a priest (Song Kang-ho) volunteers to receive a vaccination created to eradicate a deadly virus, he is given a transfusion infected by vampire blood. Acquiring super-human skills and a voracious sexual appetite, he embarks on a killing spree and a passionate affair with the wife of an old school friend. Not surprisingly, the new film from the director of ‘Old Boy’ is a darkly comic thriller that explores the nature of sin, and the pleasures of the flesh.
