In the first season of this hit series based on a true story, we meet Allison Dubois (Patricia Arquette, in an Emmy-winning role), a housewife with an extraordinary "gift" -- the ability to see and hear dead people. Her rocket-scientist husband, Joe (Jake Weber), is initially skeptical, but after a time, he becomes a believer as Allison assists police departments in solving crimes across the country.

Allison is on the mend after emerging from a coma, but she finds that her psychic abilities are manifesting themselves as a confusing form of déjà vu. Later, the murder of a neighbor puts Allison on high alert for her family's safety.

After a tumultuous previous season that saw her husband (Jake Weber) traumatized and her work with the Phoenix police department exposed, Allison Dubois (Patricia Arquette) returns to what she does best: sleuthing in the spiritual realm. In this collection of episodes from the paranormal prime-time drama's fourth year, Allison unravels baffling cases requiring more than run-of-the-mill detective work.

The second season of this drama means more of the same for medium Allison DuBois (Patricia Arquette), a suburban mom living in Phoenix who has a special gift to see what others can't. Balancing family life with a knack for solving mysteries isn't easy, but the rewards of helping others are worth it. Arquette's character is based on the real Allison DuBois, a bona fide medium and author of a best-selling book about her life.

Wife, mother and psychic Allison Dubois (Emmy winner Patricia Arquette) continues to adjust to her increasingly public crime-solving work while her daughters (Sofia Vassilieva and Maria Lark) wrestle with their newfound powers. The fifth season of the crime drama also stars Jake Weber as Allison's devoted husband, Miguel Sandoval as District Attorney Devalos and David Cubitt as Detective Lee Scanlon.

The third season of the hit show continues to follow Emmy winner Patricia Arquette in the role of psychic medium Allison Dubois as she balances life and motherhood with her ability to see dead people and look into the future. Allison struggles in working as a supernatural detective within the conservative criminal justice system, but builds credibility as she uncovers clues to grisly crimes from victims beyond the grave.

While using her powerful psychic abilities to assist Det. Scanlon (David Cubitt) in solving perplexing police investigations, Allison (Patricia Arquette) confronts tough new challenges at home with her husband, Joe (Jake Weber), and their three children. In the seventh and final season of this supernatural mystery series, Allison temporarily swaps personalities with her daughter Bridgette (Maria Lark) and starts seeing strange symbols above people's heads.

This season, Allison and her family's world is turned upside down after her abilities are publicly exposed, resulting in sweeping changes both professionally and personally.

After surviving a stroke that put her into a coma, Allison Dubois is back for an exciting Season 7 on Medium. Allison continues to put all of her psychic abilities to use in solving violent and horrifying crimes that baffle Phoenix police and others within the criminal justice system. Her daughters (Ariel, Bridgette and Marie) are also able to help their mother and District Attorney Manuel Devalos, Detective Lee Scanlon and her loving husband Joe are there to back her up.

Last season, after experiencing headaches and other symptoms, Allison is diagnosed with a brain tumor, but after she postpones her surgery, she suffers a stroke and a coma, leaving her life hanging in the balance.
