Inside the Changi Prison Complex sits Institution A4, the only women's prison in Singapore, holding around 800 inmates who make up roughly 10% of the country's prison population. This three-episode series follows a group of them through daily routines, disputes, and setbacks, with cameras granted access most prisons never allow. Nearly all the women here are connected to drugs, either through use or drug-related offenses, and the series lets several tell their own stories of addiction, arrest, and what comes after release. It also follows the all-female team of officers who run the wing, showing how they enforce discipline while building working relationships with inmates they will see every day for years. Episode titles trace an arc from arrival to reckoning: Surviving Prison, Losing It, and Will I Be Accepted?, the last one turning toward the question of reintegration once a sentence ends. The series stays close to individual inmates rather than offering statistics or policy debate, treating Changi as a specific place with specific people in it.
