Jeff and the Voltron Force are sent to attack a Drule command base, but it's well protected by an impenetrable asteroid belt. In addition, the enemy has set up a field of space mines. Luckily, before Voltron can fly into the trap, one of the Drule commanders becomes impatient and launches a pre-emptive strike. Jeff takes the chance to disrupt the Drule's plans. It won't help if he can't get past the asteroids.
