In the series finale, Yvonne chose to assist Kris in her escape scheme. Colin managed to unlock the entrance to the underground 'old prison,' but Fenner blackmailed him into revealing everything. Meanwhile, the Costa Cons were disregarded by the inmates and indulged in heroin. Fenner orchestrated Kris's downfall, sending her to the block and preventing her from joining the escape. Barbara finally tied the knot with Henry, but his family did not accept her. As Yvonne ventured into the underground prison, she was unaware that Fenner was trailing her. The G-wing inmates said their goodbyes to Denny, who was being moved to an open prison. Fenner then locked Yvonne in one of the old cells... Will anyone find her alive? Only time will tell!
