Macks Bar is one of those nice friendly places where everybody knows your name. Thats great when someones buying you a round but not so hot when you find yourself at the top of a list of murder suspects with your fingerprints on the bloody knife! Mackenzie Mack Dalton is a Milwaukee bar owner with a nose for trouble literally. A neurological glitch has left her with extra perceptive senses. So when she stumbles upon a dead body in the alley behind the bar the same spot where her own father was shot eight months earlier she can tell right away there's something fishy in the air. The lead detective thinks theres a link between the two deaths and he'll need Macks help to sniff out the murderer amid the crowd of eccentric regulars. But when all the evidence points to her as the most likely culprit it could be an early last call for Mack and celebratory cocktails for a killer.
