When 30-year-old Alexander is found brutally murdered in his Mesa, Arizona home, police are shocked - who would have wanted to harm the popular salesman with no known enemies? But soon, investigators receive a bizarre phone call that changes everything. The caller is Alexander's mysterious ex-girlfriend, Jodi Arias. This series is a comprehensive exploration of the death of Travis Alexander and the subsequent legal circus as Jodi Arias was tried for first-degree murder. Featuring all-new and exclusive interviews with key players in the case, the three-part mini-series showcases a stunning look into Jodi's bizarre, attention-grabbing behavior that led to her arrest and conviction. Notable interviews in the series include Kirk Nurmi, Arias' public defender; Juan Martinez, deputy attorney, Maricopa County; and Nathan Mendes, former detective, Siskiyou County, along with legal analysts and reporters who covered the case on the ground.

On June 4, 2008, friends found Alexander dead in the shower of his Mesa, Arizona home. He was stabbed more than 20 times, his throat was slit and he was shot in the head. Alexander's family and friends are stunned, and phone calls flood the police station with tips and information about the case. Alexander's family and friends point fingers to one key person of interest: Arias. Arias and Alexander first met in the fall of 2006 at a work conference in Las Vegas. Their meeting quickly evolved into a whirlwind relationship, and just months later, Arias is baptized into the Church of Jesus Christ of Latter-Day Saints, a faith that Alexander is strongly devoted to. But when their passionate new relationship becomes contentious the following summer, the two break up officially. Although they are no longer dating, Alexander and Arias maintain a fiery physical relationship and continue to see each other for sex for more than a year, despite Alexander dating other women and Arias moving back to California. Jealousy begins to seep into their relationship, and when Arias hacks into Alexander's Facebook in June 2008, Alexander ends things for good. After hearing the news of Alexander's murder just weeks after breaking up, Arias calls police offering assistance in any way possible. Little does she know, they have damning evidence against her; while investigating the crime scene, they discovered a digital camera that was run through the washing machine at Alexander's apartment. The recovered photos reveal that Arias was with Alexander the day he died, and even shows images of Alexander in a pool of his own blood with Arias' pants visible in the shots. And when DNA testing links hair strands found at the crime scene to Arias, a grand jury officially indicts her on first-degree murder charges in the death of Alexander. Over the next five years, Arias was tried in one of the most salacious public trials in recent history. Claims of abuse, home invasions and self-defense riddled the courtroom and her bizarre behavior provided prime tabloid fodder around the world. Arias was officially convicted of Alexander's murder in May 2013, and is currently serving a life sentence without the possibility of parole in Arizona.
