Unforgettable is an American crime procedural mystery television series created by Ed Redlich and developed by John Bellucci which follows police detective Carrie Wells who has hyperthymesia, a rare medical condition that gives her the ability to visually remember everything she has ever seen or heard.
Poppy Montgomery stars as Carrie Wells, the enigmatic former police detective with a rare condition that makes her memory so flawless that every place, every conversation, every moment of joy and every heartbreak is forever embedded in her mind.
It's not just that she doesn't forget anything - she can't; except for one thing: the details that would help solve her sister's long-ago murder.
Carrie has tried to put her past behind her, but she's unexpectedly reunited with her ex-boyfriend and partner, NYPD Detective Al Burns (Dylan Walsh), when she consults on a homicide case.
In the first season his squad included Det. Mike Costello (Michael Gaston), Al's right-hand man; Detective Roe Saunders (Kevin Rankin), the junior member of the team; and Detective Nina Inara (Daya Vaidya), a sassy, street-smart cop.
After consulting on a case, Carrie decided that she belonged back on the job and joined Al in the Queens PD. Carrie's memory helped her and Al close a staggering number of murder cases, which catches the eye of Eliot Delson, head of the Major Crimes Section of the NYPD.
Carrie and Al agree to leave Queens to join Eliot's team in Manhattan, though Carrie forces him to bring on Joanne Webster, a brilliant medical examiner well-known to Eliot for her acerbic personality.
Armed with her unique ability and backed up by the people she trusts the most, Carrie now helps protect the citizens of New York, with each case more memorable than the last.
Ed Redlich, John Bellucci, Sarah Timberman and Carl Beverly are executive producers for Sony Television Studios in association with CBS Television Studios.
The series premiered in the USA on CBS on 20 September, 2011. The series was cancelled after one season but later revived for another two on CBS. After another cancellation, the series was picked up for a fourth season by new broadcaster A&E.
