EPISODE

1. Pilot

Ninety-seven years ago, nuclear Armageddon decimated planet Earth, destroying civilization. The only survivors were the 400 inhabitants of 12 international space stations that were in orbit at the time. Three generations have been born in space, the survivors now number 4,000, and resources are running out on their dying "Ark." Among the 100 young exiles are Clarke, the bright teenage daughter of the Ark's chief medical officer; the daredevil Finn ; the brother/sister duo of Bellamy and Octavia, whose illegal sibling status has always led them to flaunt the rules, the lighthearted Jasper and the resourceful Monty. Technologically blind to what's happening on the planet below them, the Ark's leaders - Clarke's widowed mother, Abby ; Chancellor Jaha ; and his shadowy second in command, Kane - are faced with difficult decisions about life, death and the continued existence of the human race.

Complete story — includes the ending

Set in an indeterminate year in the future, 97 years after a nuclear apocalypse has devastated the surface of Earth, all known humans are residents of merged orbiting space stations known as the "Ark". 100 juvenile delinquents are sent to Earth's surface to test its habitability, having been given vitals-monitoring wristbands and instructions to proceed directly to Mount Weather. Among them is 17-year-old Clarke Griffin ( Eliza Taylor ), the daughter of the Ark's chief medical officer, Dr. Abby Griffin ( Paige Turco ). The 100 discover a lush Earth filled with new wonders and dangers. Clarke and four others search for the former Mount Weather Emergency Operations Center, a possible site of supplies. Ultimately, they discover that there are hostile survivors on the ground when Jasper, one of their party, is speared. The other delinquents remain at the landing site and, under the leadership of Bellamy ( Bob Morley ), celebrate their new world. Back on the Ark, Chancellor Jaha ( Isaiah Washington ) has been shot, causing the merciless and unsympathetic Councilman Kane ( Henry Ian Cusick ) to take charge. After Abby uses too many supplies to save Jaha, Kane attempts to execute her but, Jaha recovers in time to issue Abby a pardon.
