The 100, Season 5

Season Five begins six years later, with our heroes still separated: Bellamy’s team in space, Clarke (series star ELIZA TAYLOR) on the ground, and hundreds trapped in the bunker below. But when a massive prison ship descends upon the last survivable place on earth, The 100 must come together to reclaim their home. As two armies converge on one valley, alliances will shift, friends will become foes, and the march to war threatens to destroy all that’s left of the human race. Can our heroes break the cycle, or is humanity doomed to repeat the past? In this epic battle for survival, one thing is certain: there are no good guys. In the fifth season premiere, Clarke struggles to survive on a desolate, scorched earth, while her friends in space come across a long-awaited beacon of hope.

Octavia (series star MARIE AVGEROPOULOS) is forced to take guidance from an unlikely ally when the future of the bunker and all those inside it is jeopardized.

Bellamy (series star BOB MORLEY) leads the charge investigating a potential way home. Meanwhile, Clarke and Madi (recurring guest star LOLA FLANERY) deal with the new uncertain threat to their home.

Our heroes are forced to rely on the help of Shallow Valley’s dangerous new inhabitants in order to save some of their own – with surprising results.

Octavia leads her people towards Shallow Valley against the advice of Clarke and Bellamy. Meanwhile Kane (series star HENRY IAN CUSICK) and Abby (series star PAIGE TURCO) adjust to a new set of challenges.

Kanes's attempt to prove himself useful tests Wonkru's allegiance to Octavia. Madi faces an unexpected threat inside Wonkru, forcing Clarke to make an unlikely ally.

Clarke and Bellamy make a startling discovery about Wonkru’s battle plans as Echo (new series regular TASYA TELES) risks her friendship with Raven (series star LINDSEY MORGAN) to complete her mission.

Clarke’s determination to protect Madi puts Bellamy in an impossible situation.

The growing fractures in Wonkru threaten to explode once and for all. Meanwhile, in Shadow Valley, Murphy (series star RICHARD HARMON) starts a fire, unleashing catastrophic results.

Monty (series star CHRISTOPHER LARKIN) strives to show Wonkru an alternative to war, and to the Valley itself. Meanwhile, Abby’s health continues to deteriorate, along with McCreary’s patience. Series star Henry Ian Cusick directs.

As Clarke races to save Abby, she learns more about the trials and tribulations Wonkru faced in the bunker, and the impossible decisions they were forced to make in the dark year.

In part one of the fifth season finale, Octavia leads her people into war. While behind enemy lines, our heroes must overcome their differences to save Wonkru from extinction.

In part two of the fifth season finale, Clarke and her friends must risk everything to fight one last battle for survival – only to glimpse an even darker threat to the last living valley on Earth.

Fans get a brief and exciting look at what's in store for them in season five of The 100.

Season Four introduced our heroes to the harsh truth that the human race is doomed to face an unbeatable enemy: the remaining nuclear reactors on Earth have melted down and are setting the atmosphere on fire. Our heroes had very little time to prepare for the worst, with every possible solution disappearing almost as quickly as they were able to come up with them. With a literal countdown to the end of the world, our heroes were forced to go to unimaginable lengths to make it out alive -- with or without each other. In the aftermath of Praimfaya, they must begin again, and with Season Five our heroes will have to examine their responsibility to the new place they call home, and the future generations who will inhabit it. Can they begin again and celebrate what remains, or will the frailties of human nature cost them their one chance to rise from the ashes?
