New faces and old resentments make for a potentially volatile blend, especially now that Litchfield is a for-profit business. This season delves into the racial and economic tensions that run rampant in the halls of Litchfield. Overrun with new inmates and overseen by inexperienced guards, the prison undergoes an unprecedented culture war.

Based on the story of Brooklynite Piper Chapman, whose wild past comes back to haunt her and results in her arrest and detention in a federal penitentiary. To pay her debt to society, Piper trades her comfortable New York life for an orange prison jumpsuit and finds unexpected conflict and camaraderie amidst an eccentric group of inmates.

In the show's final season, a recently paroled Piper tries to get back on her feet while life in Litchfield, as corrupt as ever, goes on without her.
