Three people are killed in a guesthouse at a winery farm, and a fourth may have been kidnapped. Three victims, three control shots to the head—and beside the bodies, cartridge casings with unusual engraving in the shape of a snake. Apparently, this bloody massacre is the work of a professional. Soon, the criminal commits a rampage right in the center of Cape Town, and the situation escalates to the limit. The investigation is assigned to Captain Bennie Griessel and his team of detectives from the Serious Crimes Unit.
