The story is about a dying Lensman who transfers his Lens to a young man named Kimball Kinnison. To his best knowledge, Kim wasn't aware of how big the responsibility of holding the Lens is. This Lens contains vital information that would enable the Galactic Patrol to face the deadly DNA weapon created by the Boskone Empire. The Arisians initially were the ones who created the Lens in order to stand up to the evil Eddorians, because in spite of their great power, they alone could not vanquish the Eddorian menace. Through the Lens, the Lensmen minds were merged with the cosmic conscientiousness of Arisia. On another side is Lord Helmuth, the ruthless, merciless Boskone leader, who would stop at nothing to get his hands on the Lens.
