I'll Fix It is a strange bit of goods, condemning the excesses of capitalism while still allowing the chief capitalist to come off as a "good guy." Powerful businessman Bill Grimes (Jack Holt) so loves his kid-brother Bobby (Jimmy Butler) that he uses his influence to manipulate his boy's poor grades. School principal Anne Barry (Mona Barrie) at first resists Grimes' intrusion, but she allows Bobby a second chance upon realizing that Grimes is sincerely interested in the boy's welfare. Alas, Bobby betrays the trust invested in him by cheating in school and on the athletic field. Grimes turns a blind eye to this, forcing Anne and the other teachers to stage a strike, thereby neatly scotching Grimes' latest big-business deal. Despite all this, Anne rushes to Grimes' defense when he is brought up on charges of crookedness!
