Interventionist Heather Hayes enlists the help of her colleague Donna Chavous to further investigate the city's handling of the epidemic. Zac's family history of violence and drug abuse threatens to undermine his intervention. And flush with the money from his tax return, Billy and Tiffany purchase heroin and check into a hotel. It's a welcome respite from living in Tiffany's car, until Tiffany disappears.

23-year-old heroin addict Toni finds herself in danger when her pimp sends her out on a call that goes wrong. The Heroin Triangle expands its reach, putting first responders at risk, and increasing police presence in the area.

Interventionist Michael Gonzales attempts to get Toni's mother, father, and sister on the same page to intervene on Toni, but Carla's belligerent behavior threatens to derail the process before it even begins. We meet Kiersten and David, a young, heroin-addicted couple living in a co-dependent relationship with David's mother, Linda. Kiersten prepares for a mandatory meeting with her probation officer by hiding synthetic urine in her boot, in case of a drug screening.
