The Boskone blow up the agricultural planet Mqueie where Kim lives with his father, Gary ("Ken" in the Harmony Gold dub).

Having always dreamt of becoming a Lensman, Gary sacrifices his own life to secure Kim's escape from the pursuing Boskone fleet.

Through the movie's events, Kim also meets Clarissa MacDougall, a nurse and technician working with the Galactic Patrol.

Through the tutelage of a flying alien green dragon hero named Worsel, Kim gradually realizes the Lens's power, which provides the key to Helmuth's defeat.

He transmits the formula to the Galactic Patrol fleet, knowing that their planned attack against Helmuth would fail without the answer.
