Five teenagers are chosen from across America to do battle with an invading Alien empire. They are not warriors, they are but children, but they are humanity's only hope.
As the battles against the alien forces begin to become more and more mundane the Rangers meet a new friend, all while Bandora searches for the Rangers on her own.
While Jason and Tommy are having trouble deciding who should lead, the threat of larger battles ahead have the Rangers set out to find the seventh and final Zord: Titanus.
The Rangers must do battle with pure evil in the form of Lord Zedd. The stakes have never been higher and the price of failure is a fate worse than death.
