After taking down a man wielding an AR-15 a small town winery, Rushmore McKenzie has to find out who, if anyone, was the shooter's target before he, or someone else, tries again.
Once a police detective in St. Paul, Minnesota, Rushmore McKenzie, after becoming an unexpected millionaire, now is an unlicensed private investigator, doing the occasional investigative favor. Off on a weekend getaway to northwestern Wisconsin, McKenzie, with a group of five, including his childhood friend and current police detective Bobby Dunston, stop off at a local winery. When a man walks up carrying an AR-15, which he raises, props the butt against his shoulder, and sights down the barrel - but before he can do anything, Bobby Dunston yells 'gun' and he and McKenzie take the man down.
