Fatal Vows

When marriages fall apart, divorce can turn ugly - even deadly. From blushing brides turned cold-blooded killers to smitten grooms with shocking dark sides, "Fatal Vows" examines the criminal psychology behind deadly divorces. Guiding viewers through actual stories of love gone wrong are psychotherapist Stacy Kaiser and forensic/clinical psychologist Dr. Brian Russell, who examine each couple to better understand how the marriage turned from flawed to fatal. This documentary series explores tumultuous, shocking and high-stake divorces and the deadly murders linked to them.

Stylized re-enactments are supported by interviews with family, friends, law enforcement, and potential victims of the crime, while Kaiser and Dr. Russell provide analysis on unions that break down until divorce and murder collide.
