The elite team of FBI agents in the Behavioral Analysis Unit (BAU) will be led to Upstate New York to investigate unusual stabbings and a murder case in the next all-new episode of "Criminal Minds" on March 19.

Just as the probe wraps up a murder investigation, Morgan's search for answers from one of the crime's survivors causes him to realize that all of the questions in the case have not been answered.

In a promo for the upcoming episode, "The Edge of Winter," a woman recalls the horror she endured for 10 months at the hands of the criminals. Because she can't escape the terrifying memories, she seems to suffer from PTSD and lets out a chilling scream.

According to Hollywood Hills, CBS issued a press release with a synopsis that reads: "As the BAU wraps up an investigation into unusual stabbings in Upstate New York, Morgan's visit with one of the crime's survivors might uncover more questions left for the team to answer."

Guest stars in Episode 19 include Taymour Ghazi as Joe Bachner, Marty Fortney playing Dad, Aasha Davis as Daria Samsen and Lisa Kaminir in character as Dr. Carol Roberts, reports TV Guide. Other guest stars will include Guy Nardulli playing Det. Walker, Isabella Way as Nurse, Matthew Alan Brady as Lionel, Marty Fortney as Dad and Aaron Fili as M.E. Garrison.
