New York’s 16th precinct is under siege by the flu. Detective Nick Larson and his partner, Victor Sacco, are up to their armpits with work overload. The captain’s cigar is seriously chewed and everyone is working around the clock. To complicate matters, on a personal level, things aren’t going smoothly, either, at least not until he gets his act together. But when Nick’s captain assigns a new case, a suicide, Nick’s instincts start issuing alarm bells. And it would be just his luck, after discovering similar suicides around the area, that they may just have a serial killer on the loose.
