Risan, a member of the Candaran federation council on the planet Candara, uncovers a fiendish plot. Some of the members are conspiring to overthrow the council. They wish to impose their will upon its citizens. The Candarans are an intelligent and advanced race of symbiotic beings. They have the abilities to meld with and manipulate organic life-forms on a molecular level. They are humanoid but with a different physiology.
Risan is marked for assassination after discovering the nefarious plot. The group of powerful traitors try to eliminate him before he can expose them to the council. He escapes his home world, only to be hunted and pursued through space by an evil commander named Solrac and his two underlings. The chase takes them to the Milky Way galaxy via wormholes. Hit with a near-fatal, blast Risan crashes on a third planet orbiting a sun. There he sinks to the bottom of a lagoon on a tropical island, lying dormant until the fateful moment he comes in contact with his host-a humble farmer who is unaware of the dramatic events that will change his life forever.
Meanwhile after being battered going through an asteroid belt that circles the planet, the three nefarious beings crash on a beachhead, where they meld with three unscrupulous humans and begin a campaign of terror on the island and its inhabitants.
