At the Western Massachusetts Regional Women's Correctional Center, a new arrival named Vanessa enters custody pregnant and in heroin withdrawal, with the possible loss of her unborn child hanging over her stay. The episode follows her detox on the ward, cameras present for the physical sickness and the fear underneath it, as staff and fellow inmates weigh in on what happens next. Interviews with corrections staff and other women held there widen the picture beyond Vanessa's cell, showing how often addiction, poverty, and pregnancy collide inside the same institution built mainly to hold rather than treat. The facility itself becomes a kind of character: overcrowded, underfunded, staffed by people who describe a system with few tools for second chances. Rather than editorializing, the episode lets the detox process and the offhand conversations carry the argument about what incarceration actually does to a pregnant addict. It is the first episode of a series on women's prisons, grounded entirely in observational footage and on-camera interviews rather than reenactment or narration-heavy exposition.
