On Mickey's birthday, Miss Pipps, the school teacher, serves cake and ice cream during school hours. Sour old Mr. Pratt, head of the school board, stumbles on the festivities and has Miss Pipps fired. The Our Gang conspire to save her job by inviting all the parents to a special meeting. There the gang stage a melodrama, with Mr. Pratt portrayed as Simon Legree. The parents react by demoting Mr. Pratt to janitor. They appoint kindly Mr. Swanson, the current janitor, to head the school board. And of course they reinstate Miss Pipps as school teacher. Sometime later, in an act of forgiveness, Miss Pipps and the gang hold a birthday party for Pratt who is then humbled by the experience.
