Voltron, Defender of the Universe: Vehicle Voltron

The Voltron Force is attacked near planet Eldora when the local people mistake them for the Drules. Jeff is taken prisoner and tries to reason with them, but a nearby Drule commander realizes what's going on and demands Jeff's release, insisting he is one of the Drules. Jeff has no choice but to escape on his own, or the team won't be able to form Voltron in time!
