After a disastrous riot at Barfield Prison, Helen Hewitt joins an investigation team tasked with looking into a suspicious death. When the governor of Barfield is ousted, Helen takes the job, becoming the youngest woman in charge of an all-male prison and causing resentment among both prisoners and officers.

Barfield wakes up to a tragedy involving Alan as Helen prepares for an important visit from headquarters. Maureen leads a drama group, but Helen and the officers believe she's getting too close to Norman. Anthony and dealer Snoopy plan a hit on their tormentor, Braithwaite.

Now reinstated as governor of Barfield, Helen tries to comfort the prison psychologist, Annette. Snoopy's sentence is extended, although he doesn't remember what he did in a drug-fueled rage. Brathwaite receives a visit from his father.

Helen's television appearance doesn't go as planned when she is blindsided by the prison refurbishment costs. Tensions are high as a prisoner attempts to escape, a cell is burgled, and a wealthy new inmate arrives.
