The Arnos are still in Las Vegas, where Danny's assignment-to protect Linson, a casino owner and former mobster who's been cooperating with the FBI-has taken a turn for the worse. Without telling Danny, Linson has sold his casino to known mobster Lon Columby, and has now mysteriously gone missing. What's the real story behind the sale? Even worse, the sale means Columby is now the boss at the nightclub where Danny's been resurrecting his lounge act-and one of Columby's first moves is to fire Danny. Danny appeals to Ellen Lederer (photo attached), another FBI agent who's been working the casino, for help, but her personal relationship with Columby may get in the way of bringing him to justice. Now Columby is bringing in his old Mob cronies to help him create his vision of a new (and Mafia-controlled) Las Vegas-and the best hope for stopping him might just be his mother.
