When viewers were last in Litchfield, Piper was released after her wedding to Alex, Taystee was sentenced to life in prison after BFF Cindy lied on the stand and the prison was nearly torn apart by feuding sisters.  
Now in season seven, Piper has to get back on her feet outside of Litchfield, Taystee is adjusting to her life sentence, Gloria (Selenis Leyva) and her kitchen staff see just how Polycon is making money now, and life goes on for other inmates.
