3x17 - Voltron: Defender of the Universe

Lotor tries to attack Zarkon from behind. Zarkon catches him in the act, and orders his arrest. Meanwhile on Arus, a young woman asks the Voltron Force for help for her sick mother. Her mother had come upon Haggar, and the witch responded by casting a spell to make her ill. Allura gets a vision from King Alfor's ghost telling her that the way to break the spell is from a magic cadmium flower. When the flower blooms, Haggar sends her blue cat to steal it. The team follows her to Planet Pollux, where they find out that Zarkon is building a secret military base. When the Ro-Beast attacks, the Voltron Force is aided by an unlikely ally.
