Someone enters the Castle of Lions by night and only after Pidge attacks the one who refuses to give a name is it revealed to be Allura's former governess, Nanny. Later, Allura sneaks out in the Blue Lion to work up to the point where she can pilot as a replacement for Sven, but crashes. She is set on learning, but Coran and especially Nanny are against the idea. But another Robeast attacks Arus without Voltron to stop it, and Nanny's life is threatened when she goes to the village to find a substitute, so Allura must escape from where Coran has imprisoned her and join the others as the only hope to stop it.
