Ep 21. Murder in Greenwich

In Plain Sight is an American crime drama television series that aired on USA Network from 2008 to 2012. The series focuses on Mary Shannon, a Deputy United States Marshal who works in the witness protection program and her personal and professional relationships.

Season 1 episode 21 of In Plain Sight is titled "Murder in Greenwich." In this episode, Mary and Marshall have to protect a Federal witness who is a key player in a murder investigation in Greenwich, Connecticut. The witness, Linda Plager, is a decorator who was hired by the wealthy family of 15-year-old Martha Moxley. Linda was working on the Moxley's house the night Martha was brutally murdered with a golf club.

Linda had seen Martha's brother, Tommy, and his friend, Michael Skakel, around the house that night. Tommy and Michael were the main suspects in Martha's murder, but the case went unsolved for years due to the influence of the Moxley family. However, the case was reopened when Tommy wrote a book confessing to the murder. Tommy was eventually convicted and sentenced to 20 years to life in prison.

Now, years later, Linda has come forward with new information implicating Michael Skakel in the murder. Michael is the nephew of Ethel Kennedy and was 15 years old at the time of the murder. He was also a suspect in the original investigation but was never charged.

Mary and Marshall fly to Connecticut to protect Linda while she testifies in front of a grand jury. Linda is reluctant to testify since she fears for her life. She has received threatening phone calls and believes that someone is watching her. Mary and Marshall try to reassure her and make her feel safe, but Linda's fears continue to escalate.

Meanwhile, Mary and Marshall try to identify and protect potential witnesses who could corroborate Linda's story. They interview the Moxley's former gardener, who heard noises coming from the Moxley's house the night of the murder. They also interview a former babysitter for the Moxley's, who saw Tommy and Michael leave the Moxley's house together that night.

As Mary and Marshall race to protect Linda and gather evidence against Michael, they discover that the Moxley family is still using their wealth and influence to protect Michael and keep the truth from coming out. They face opposition from local police, prosecutors, and even the FBI, who believe that the case is closed and that they should not be meddling in their affairs.

As the grand jury date approaches, Mary and Marshall work tirelessly to ensure Linda's safety and gather enough evidence to convict Michael Skakel. However, they soon realize that the case is much larger than they initially thought, and they are not sure who they can trust. The tension builds as they race against time to bring a killer to justice and protect the innocent.
