This episode is supposedly taking place in the Tetons, a gorgeous mountain range in Northwest Wyoming (near Yellowstone). Of course, like most other episodes, it was filmed in Hollywood.
When Jessica arrives at a resort in the Tetons, she soon notices that a man named Nichols, as he's apparently hated by several people there. One is his ex-, who he used to beat up before she got the courage to leave him. Another is an ex-colonel who is going to be running for office...and Nichols keeps telling everyone that the colonel is a killer. And, finally, when a diamond is stolen at about the same time as Nichols is found dead, it could be his confederate in the theft did it. Or, there could be a fourth person, as Nichols seems to attract folks who dislike him!
This is a pretty good episode and the murderer might catch you by surprise. Well worth seeing...even if it's not the Tetons.
