In the series premiere, 100 young exiles from a dying space station are sent to the planet Earth 97 years after a nuclear apocalypse to see if it's habitable.

Having discovered that Jasper may still be alive, Clarke, Bellamy, Octavia, Finn and Monty set out on a mission to locate their friend and are shocked at what they find. Meanwhile, on the Ark, Abby is determined to get to Earth, and enlists Raven (guest star LINDSEY MORGAN) to craft an escape pod.

After the shocking death of one of their own, Clarke and Finn grow closer as they try to figure out a way to communicate with the Ark. Bellamy must keep the group from turning on one another as life on Earth takes a desperate turn. Meanwhile, Abby risks having herself floated in order to give Raven (recurring guest star LINDSEY MORGAN) the chance to stow-away in the escape pod bound for Earth.

Clarke makes a desperate plea with a former allied force in an attempt to avoid a war and ensure the survival of her people.

As tensions rise in Arkadia and Polis, Jaha leads Clarke and Bellamy down a road toward possible salvation.

While Abby leads a team to a distant location, hoping to find answers, the continued struggles with leadership and trust in Arkadia and Polis take a violent turn.
