Among them is the dangerous, highly lethal drug “Anthem” which casts a dark shadow over the city. The SEVEN-O Special Crime Investigation Unit specializes in cracking down on Anthem. This unit operates in two man “buddy” teams in what’s called the “Double Decker System” to tackle the problem. Doug Billingham is a seasoned investigator, and joining him is Kirill Vrubel, whose abilities are mysterious and unknown. less
