When is Will Ruby not Will Ruby? When he's working undercover. This time, it's for a movie shoot. The studio has received anonymous warnings threatening to sabotage the project. Will figures out pretty quickly it has to be someone on set. But who? The leading man? The key grip? Surely not the cook; she makes the best chili Will's ever had. It'll take a bit of wrangling, but, with the help of his sister, Harry - who's a stuntwoman on the shoot, his Homicide Lieutenant brother, George, and a bit of movie magic, he'll get his man.
