Cloud Strife, a mercenary with a troubled past, is hired by the eco-terrorist group AVALANCHE to strike at the Shinra Electric Power Company — a mega-corporation that harvests the planet's life energy for profit. Initially motivated by money and a promise to childhood friend Tifa Lockhart, Cloud is pulled into a conflict that reaches far beyond corporate greed: Sephiroth, his nemesis, has returned, and the planet itself may not survive what comes next.
