Cameras go inside Institution A4 at Singapore's Changi Prison Complex, the country's only women's prison, where about 800 inmates are held, most for drug use or drug-related offenses. This opening episode of a three-part series follows six women navigating daily life behind bars alongside the all-female officer corps who supervise them. Joanna's rising frustration pushes her toward a breaking point that threatens her chance at release. Christeen, fourteen years into her sentence, receives a rare visit from her estranged son. Juliana confronts her own history when she comes face to face with her imprisoned daughter, while Haziqah gets devastating news about her son from outside. Yuxin and Halen show the smaller textures of confinement, from scavenged pleasures to the risks of taking on responsibility as an inmate leader. The film builds its picture of prison life through these overlapping stories rather than narration, letting routine, tension, and the guards' daily rounds carry the episode.
