Sharon Raydor (Mary McDonnell) and her team of operatives will have their mettle severely tested in the upcoming episode of the TNT series "Major Crimes."

In "#FindKayla," CarterMatt reports that the daughter of a baseball hero goes missing. The unit is tapped to investigate her disappearance, but it will soon be obvious to the operatives that this is no ordinary case. In fact, they themselves will question if the justice system they have sworn to uphold is enough to vindicate what happened to an innocent little girl. Meanwhile, Rusty Beck (Graham Patrick Martin) will find himself between a rock and a hard place as Slider's (Garrett Coffey) trial comes to a close.

After Mariana aka Alice Herrera's (Jade Bender) brother stormed out of the court room upon leaning his involvement with the criminal, Rusty has been feeling guilty. Ever since he covered the Slider trial, he has stopped corresponding with Gustavo (Ramón Franco). Rusty told Sharon he did not want Mariana's brother to know of his connection with her killer. He said he dreaded the moment when Slider waved at him during the trial and Gustavo would get the wrong idea.

It turned out Rusty's apprehensions were spot on, as Gustavo was livid at him for befriending Slider. The situation became worse when Rusty was informed that he has to testify for Slider during his sentencing. Monroe (Greg Rikaart) even emphasized that he was Slider's only friend, making Gustavo angrier. Rusty reminded Monroe of their deal that he would not be asked to go to the witness stand for the trial. Monroe, however, told him that the hearing was finished already, with Slider being found guilty on all accounts. This time, he has no choice but to bear witness to his sentencing.

"Major Crimes" airs Mondays at 9 p.m. EST on TNT.
