Unforgettable is an American television drama that aired on CBS from October 1, 2014 to September 14, 2014 and moved to A&E from November 27, 2015 to January 22, 2016.

Summary
Former Syracuse, New York, police detective Carrie Wells has hyperthymesia, a rare medical condition that gives her the ability to visually remember everything. She reluctantly joins the New York City Police Department's Queens homicide unit after her former boyfriend and partner, Lieutenant Al Burns, asks for help with solving a case. The move allows her to try to find out the one thing she has been unable to remember, which is what happened the day her sister was murdered.

As season two begins, Carrie and Al are offered a transfer to the NYPD's Major Crimes Section, leaving the 117th Precinct in Queens. Dr. Joanne Webster is the only supporting character to go with them.

Cast

 * Poppy Montgomery as Carrie Wells
 * Dylan Walsh as Lieutenant Al Burns
 * Jane Curtin as Dr. Joanne Webster (Season 1-3)

Development
The hour-long program is based on J. Robert Lennon's short story "The Rememberer". The series was created by Ed Redlich and John Bellucci and co-produced with Carl Beverly and Sarah Timberman for CBS, where it made its debut on September 20, 2011. The series is a co-production of CBS Television Studios and Sony Pictures Television. On October 25, 2011, CBS picked up the series for a full first season of 22 episodes.

Serving as a consultant on the series is actress Marilu Henner who, like the series' lead character Carrie Wells, possesses hyperthymesia in real life. She had a guest spot in the episode "Golden Bird", as Wells' aunt, who is suffering from symptoms similar to that of Wells' mother's early-onset Alzheimer's disease.
