Allison is confused when her dreams of a man murdering his wife keep occurring, even after she helped Devalos convince the jury of the suspected killer's guilt. Through her troubles she manages to make a new friend named Debra. Meanwhile, Joe is frustrated by the therapy sessions that his job enrolled him in, and can't express his feelings to Allison because the recent hostage situation he was in is still greatly affecting him.

The investigation of the murder of Walter Paxton's wife continues, as it is now determined that a serial killer is on the loose. While helping Devalos and Scanlon with the case, Allison discovers that her new friend Debra is the next victim. Allison goes to great lengths to protect Debra, but is shocked to find that her new friend isn't who she thought she was. Meanwhile, Joe debates being part of a lawsuit against Aerodytech, the company he's been loyal to for years.

In the third season finale, Allison's life, along with the lives of her family, is uprooted as her psychic abilities are revealed to the public. Allison must now find a way to catch the "recapitator" serial killer on her own, as she can no longer turn to Devalos or Scanlon for help.
