According to Netflix, in the final season, the Litchfield inmates 'come to terms with the fact that prison has changed them forever'.
The plot summary explains: "Piper struggles with life on the outside, while life in Max, as corrupt and unjust as ever, goes on without her. Taystee's friendship with Cindy still hangs in the balance as her life sentence looms, Gloria and her kitchen staff are confronted by the hard truth of Polycon's newest profit stream, while others chase drugs or dreams and grapple with the reality of their place in this world."
Netflix broke the news that the seventh season of the series would be its last with a poignant video that featured messages from the cast, warning fans on Twitter: "This will make you cry."
Taking it in turns to speak, the cast said: "We've got some news... The final season is coming."
They then individually recounted what it had meant to work on the show, with Uzo Aduba (Suzanne 'Crazy Eyes' Warren) saying: "I'm so grateful for the fun times, the knowledge, the friendships, the love, the family that we have created together."
She added: "Season 7, you will not be disappointed. It is a season you will not forget, and we're going to give you everything and more that you have ever wanted."
Laura Prepon also said that their 'relationships will continue' after the show, while Taylor Schilling thanked fans for all their support.
Based on the book of the same name by Piper Kerman, the critically-acclaimed show is one of Netflix's longest-running and most popular series. It's also been the winner of countless awards, as well as multiple Emmy nominations.
"After seven seasons, it's time to be released from prison," showrunner Jenji Kohan said at the time of the show's cancellation.
"I will miss all the badass ladies of Litchfield and the incredible crew we've worked with. My heart is orange but fade to black."
