Jeff Walker, a Martian colonist is trapped in another universe, and lands on an island on a far away planet. He is befriended by its inhabitants, the Lingworts and learns to live in peace. When an outside alien force threatens their way of life, he must join an intergalltic war that he wants no part of. When a leader of a supposedly peaceful federation steals a weapon of mass destruction, Walker and his band of misfits must stop him, before all races are exterminated. Unaware to Walker, however, is that the key to their survival lies deeply rooted in his own world's past.
