Voltron continues the attack on Planet Doom with Merla's help. This time, Lotor is by her side, ready to take on his father and lead Voltron though Haggar's traps. Zarkon takes hostages and hides behind his slaves, but Lotor sees through the trick. Are Keith and the Voltron Force finally going to take out Zarkon, or is Lotor planning the biggest double-cross yet?
