The Behavioral Analysis Unit (BAU) will take on a new unsub with a penchant for enslaving his victims in the upcoming episode of the CBS series "Criminal Minds."

In "Hostage," CarterMatt reports that the case will come to the attention of the FBI when a teenager claims she has been kidnapped and held captive for years a by a deranged man. The 18-year old girl said she escaped from the unsub's lair, a suburban home, but there are two other women still left in the house. Aaron Hotchner (Thomas Gibson) and his team have to figure out why the criminal has been abducting women and enslaving them for years. They also need to find the community where he is smart enough to hide his victims without incurring the attention of his neighbors.

Last episode, an unsub who wanted to settle an old grudge caused havoc in the South, where he displayed the body of his victims in truck shops. Before the BAU could get to him, he already killed twice. The group had difficulty finding the connection between the two murders, until they stumble on his true identity from a foster home. It turned out that when he was a kid, the court ordered that he grow up away from his mother. His teacher noticed signs that he was being abused and promptly brought the case to the authorities.

His first victim was a court worker that time, while the second, his former teacher. The unsub wanted revenge, but not because he blamed them for what had happened. In truth, it was his mother who told him to kill. The old woman, who was imprisoned in an asylum, was relaying orders to his son on how to murder people. When she was younger, she was sexually assaulted by a trucker. Ever since, she had schooled her son to hate drivers. She committed six murders before she finally got to her rapist. It was also her modus to showcase the body in truck houses.

The BAU managed to stop her son from killing his longtime girlfriend. The mother was jealous of their connection. She influenced him to murder her so that nothing would come in between them. At the end, when the unsub was put in psychiatric care, he cut off his own ears so prevent her from manipulating him ever again.

"Criminal Minds" season 11 airs Wednesdays at 9 p.m. EST on CBS.
