Unforgettable (1996)

Ray Liotta stars as David Krane, a medical examiner who has been acquitted for his wife’s murder. Obsessed with finding the real killer, a possible solution presents itself in an experimental serum designed by a neurobiology professor (Linda Fiorentino), which has the ability to transfer memories from one person to another, but with potentially fatal consequences.
