Plot Synopsis

A DEADLY DOSE is a three-part documentary series that chronicles the 2015 death of attorney and part-time judge Susan Winters at her home in Henderson, Nevada. When Susan, a wife and mother of two, dies from ingesting antifreeze and oxycodone, it's initially ruled a suicide. But her parents suspect that Susan's husband, Gregory "Brent" Dennis, is behind it. Can their attorney find enough evidence against their son-in-law to pursue a case? As Brent's drug use is exposed, witnesses defend him -- including his assistant and his daughter, who both claim Susan had a dark side others didn't know about. But when phone records reveal more of Brent's lies, the team decides to put him under oath. In the wake of Brent's fiery deposition, new witnesses emerge that paint Susan as suicidal. Tony's team soon believes that the missing family computer holds the key to the case. Can they find enough evidence without it to implicate Brent in Susan's death?
