Pick of the day: The Prisoners
9pm, BBC1
The first episode of this new three-parter follows repeat female offenders from Holloway.
Jayde is 18 but has been in jail six times. Stuck in a cycle of reoffending, she manages two weeks in the outside world before returning to prison.
Crystal, 23, has been a regular inmate since she was 17. On release she returns to her estate but fears the environment will cause her to relapse. Each story is different but they share a shocking truth: many offenders feel more at home in prison than out.
