After Voltron's victory over Lotor and his army, the Robot Lions lost control during a celebratory event and nearly destroyed a city. Because of this, Galaxy Alliance commander Sky Marshall Wade ordered the Lions to be dismissed from their duty as defenders of the universe and disbanded the Voltron Force. Since that day only the Galaxy Alliance has been in charge of protecting the universe while Lance, Pidge, and Hunk are acting officers in the army, Princess Allura is ruling her home planet Arus, and Keith is a fugitive from the Alliance. Daniel is a mischievous and curious student in the Galaxy Alliance air school. Daniel and fellow student Vince are recruited into the Voltron Force as junior cadets and later become members of a resistance against Sky Marshall Wade, during which Keith infiltrates Wade's secret base and searches for the Black Lion. Now, as part of the resistance's plan, Daniel and Vince sneak into Wade's room and switch out his prized pin with a fake one and head back to "The Den", the resistance headquarters. The reason is that the 4 insignias on the pin are actually the keys to reactivate the Lions. Meanwhile, Keith discovers his Black Lion and breaks it and himself out of the base, contacting Pidge and trying to escape Wade's security.
