Mickey Mouse Theater 1938 - Cinderella

When Cinderella is a young girl, her widowed father marries Lady Tremaine, a widow with two daughters of her own, but dies shortly thereafter.

Lady Tremaine, jealous of her stepdaughter's beauty and determined to forward her own daughters' interests, orders Cinderella to become a scullion in her own château, overburdening her with chores. Cinderella's stepsisters, Anastasia and Drizella, also take advantage of her meekness, mocking her and adding to her workload.

Despite this, Cinderella remains kind of heart, obediently doing her chores whilst taking care of the mice and birds that live in the château, making friends of them, mainly of two mice named Jaq and Gus. She also protects them from being eaten by her stepmother's cat Lucifer, who makes her duties even harder in retaliation.
