As the film is revealed to be a dream/premonition, it's not clear if the murders or her death happened/will happen or not.
Bio[]
Nine years or more prior, Martin was married to an unnamed woman. Unbeknownst to his first wife, Martin was sleeping with Andrea behind her back. The pair both hated the woman and wanted to be together, so they arranged her murder via Andrea stabbing her to death and making it look like a burglary gone wrong. They married soon after, but Martin got into a car accident, which paralyzed him from the waist down and left him unable to satisfy Andrea.
