Shaz and Denny introduce Buki to their secret tunnel from the shed; Yvonne and Maxi finally come
to blows and Governor Grayling begins to get a bit too friendly with his new tenant - Jim Fenner.
Unfortunately the series has started to slide downhill with the introduction of inmates Cassie and more specifically
Roisin who are, in my opinion, a frustrating distraction from the great storylines from the past three series.
