From IMDB:

A thriller that tells a traumatic murder story through the eyes of three central characters: Carrie the daughter of the murdered woman, Douglas Hain the detective in charge of the investigation, and Sally the murder victim.

From Amazon Prime  you can stream this 1 hour 57 minute full film.

Douglas Hain is an unhappily retired police detective. Carrie runs away from her wedding ceremony because she feels she cannot lead a normal life until she finds out who brutally stabbed her mother to death.  In a determined way Carrie starts digging which leads her to Hain who was the detective that worked on the unsolved cold case.

First impression is that Hain was the killer because he was romantically involved with the victim.  As the story develops using many flashbacks,  little by little the crime details come forth. Expect a bit of a surprise ending.

Sharon Small (played Rose Marshbrook in The Bay which we recently reviewed)  as Dr. Laura Maitland is one of the more familiar actors.

Nothing to criticize in this well-acted suspense thriller.
