(August 2018) </Td> </Tr> <P> The series begins revolving around Piper Chapman (Taylor Schilling), a woman in her 30s living in New York City who is sentenced to 15 months in Litchfield Penitentiary, a minimum - security women's federal prison (initially operated by the "Federal Department of Corrections". This is a fictional version of the Federal Bureau of Prisons . In later seasons, it was acquired by the Management & Correction Corporation (MCC), a private prison company) in upstate New York . Chapman was convicted of transporting a suitcase full of drug money for her girlfriend Alex Vause (Laura Prepon), an international drug smuggler . The offense had occurred 10 years prior to the start of the series and in that time Piper had moved on to a quiet, law - abiding life among New York's upper middle class . Her sudden and unexpected indictment disrupts her relationships with her fiancé, family and friends . In prison, Chapman is reunited with Vause (who named Chapman in her trial, resulting in Chapman's arrest) and they re-examine their relationship . Simultaneously, Chapman, along with the other inmates, attempt to grapple with prison's numerous, inherent struggles . Episodes often feature flashbacks of significant events from various inmates' and prison guards' pasts . These flashbacks typically depict how the inmate came to be in prison or develop the character's backstory . </P> <P> The fifth season shows the prisoners revolting against the guards, wardens and the system after MCC's failed handling of an inmate's death at the hands of a guard . This followed a peaceful protest and subsequent instigation of an inmate fight by another guard in the fourth season . Fueled by the conditions the inmates are forced to tolerate, as well as grudges against the prison guards, a three - day riot ensues, during which some inmates attempt to negotiate better living conditions and seek justice for the death of the inmate, while others pursue their own interests and entertainment, and a few seek no involvement in the riot . At the emergence of the riot, the guard that incited the fight in the prior season is critically shot by an inmate who took the gun the guard illegally brought into the prison . At the end of the season, SWAT raids the prison to end the riot and remove all inmates from the facility . During this raid, a correctional officer is fatally shot by a corrupt "strike team", which then conspires to blame the guard's death on inmates that hid in an underground bunker and had taken hostage of the guard . All inmates are transported to other prisons . </P>
