In women's prison Lindburg, inmate Lena Möller is murdered. Prime suspect thug inmate Vera Kämper, shortly before her release, takes hostage jailer Conny Küppers, and police detective Katharina Hahn, who got Lena arrested and visited at her demand, demanding that 'the real culprit is found', while warden Renate Reimann called in a SWAT team. Team Bauer must work out all dirty prison secrets, involving complex drug trade interests, lesbian exploitation and even a seemingly altruistic bone marrow donation for the incompetent warden's kid son.
