Ep 4. Whistle Stop

In Plain Sight season 3 episode 4, titled "Whistle Stop," follows U.S. Marshal Mary Shannon and her partner Marshall Mann as they work to protect a witness named Stuart Morris from a dangerous criminal organization known as the Michener Group. Morris is a former employee of the Michener Group who has turned informant, and the organization is determined to silence him before he can testify against them in court.

The episode begins with Morris being rushed to the hospital after being shot by a member of the Michener Group. Mary and Marshall hurry to the hospital to check on him and begin their investigation into the shooting. They soon discover that the Michener Group has set up a network of corrupt cops and judges to help them avoid prosecution. Mary and Marshall realize that they need to go off the grid in order to protect Morris and stay one step ahead of the Michener Group.

To that end, Mary comes up with the idea to take Morris on an old-fashioned train ride, using an antique steam engine train as a way to transport him to a safe house in a remote part of the country. They board the train at a small station in New Mexico and are soon joined by a colorful cast of characters, including a group of senior citizens on a vacation, a family on their way to visit relatives, and a bickering couple who are trying to rekindle their relationship.

As the train makes its way through the scenic countryside, Mary, Marshall, and Morris try to stay low-key and avoid drawing attention to themselves. However, the Michener Group soon catches wind of their whereabouts and sends their henchmen to track them down. Mary and Marshall must use all of their skills to outsmart the Michener Group, avoid the corrupt officials who are working against them, and protect Morris until they can get him to safety.

Throughout the episode, we see flashbacks of Morris's life before he turned informant and the events that led him to work for the Michener Group. We also learn more about Mary and Marshall's complicated relationship, as they continue to navigate their professional and personal lives while working together.

Overall, "Whistle Stop" is an action-packed episode that combines suspense, humor, and heart as Mary, Marshall, and Morris try to stay one step ahead of the Michener Group. The train ride serves as a unique and creative setting for the episode, adding an additional layer of excitement and tension to the already-compelling storyline. Fans of In Plain Sight will appreciate the show's trademark blend of drama and humor, as well as the strong performances by the cast.
