A Deadly Dose

When Susan, a wife and mother of two, dies from ingesting antifreeze and oxycodone, it's ruled a suicide. But her parents suspect that Susan's husband Brent 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.
