There's an alert at HMP Downview women's prison when repeat offender Collette O'Flaherty, distraught at missing out on a place at the prisoners' family day, takes a fellow inmate hostage. A prisoner at HMP Portland hears false rumours that he is a sex offender - and suspects the culprit spreading the lies is a new officer. The inmates at HMP Bullingdon look forward to Friday, when they receive small treats like chocolate and shower gel - but dealing in these items quickly leads to violence.
