The Knight Is Young (1938)

June never leaves her apartment, which has a view of an advertising sign of a knight in shining armor. She is two weeks behind in her rent and believes that if she leaves the apartment, the landlord will never let her back in. The only way she gets food is when her friend, singer Earlayne Schools, brings it to her. One evening June sees Hal, a tap-dancing sign painter, painting over her knight. She explains her predicament, and he does his best to help her out.
