This week an all new episode of Prodigal Son.

Bright jumps at the chance to help Arroyo solve a quadruple homicide for the NYPD. As Bright slips into the mind of this serial killer, he finds himself dealing with the repercussions of seeing his father for the first time in years. Tormented by the terrors of his childhood, Bright is faced with a question: are his dreams just nightmares or did they actually happen?

Malcolm gets his dream interview opportunity when the NYPD zeroes in on one of his and Martin’s favorite psychologists, Dr. Elaine Brown (guest star Sakina Jaffrey), who may be involved in a homicide linked to an LSD-laced psychology trial. Meanwhile, as his night terrors continue to evolve, Malcolm checks in with his trusted childhood therapist to discuss new theories on what exactly he witnessed as a child, and the consequences of Malcolm’s visits with The Surgeon begin to add up when Gil, Jessica and Ainsley catch wind that he has been seeing his father again.

As Malcolm's childhood memories surface, he realizes his father's killing spree may not have been a surprise to everyone in the family; Malcolm, Gil, Dani and JT hunt for a stalker with a creepy eye for design.

Malcolm searches the depths of his mind to unravel the mystery of the girl in the box; when the NYPD investigates a homicide and assumes it is linked to a drug cartel, Malcolm discovers a secret about Dani's past that draws them closer together.

When Bright uncovers a photo of himself and Martin from when he was a kid, he is forced to focus on the repressed memories from his childhood psyche; Jessica and Malcolm agree they must put a stop to Ainsley's idea.
