Zack Bowen and Addie Hall were both young and beautiful - charismatic fixtures of New Orleans' bohemian French Quarter in 2005. But they were also a pair of damaged souls. A free spirit who wrote poetry and taught dance, Addie was also on the run from a troubled past. And Zack wasn't just the beloved bartender and talented musician known throughout the Quarter; he was an Army veteran scarred by his time in Kosovo and Iraq. Zack and Addie fell in love just weeks before Hurricane Katrina, but the bond they formed couldn't survive in its wake. As the city slowly recovered, Zack and Addie's relationship deteriorated, their passion for each other spilling over into clash after clash - until Zack could no longer keep his demons at bay, and a murderous night changed everything. Told from the victim's point of view, this episode of "Final Witness" includes gripping, first-person accounts of the murder case by Zack and Addie's friends, Zack's mom, Addie's employer and others.
