The first part of the film explains the anatomy of the abdomen using diagrams and animations. The position of the appendix is shown and an animation shows the progression of inflammation in an appendix, resulting in appendicitis. The intertitles explain the possible consequences of appendicitis. The symptoms of appendicitis are listed, and the intertitles note that in the case of severe, persistent abdominal pain, a doctor should be called and the pain should not be treated by castor oil or other cathartics. The second part of the film is a dramatisation of a case of acute appendicitis. The daughter of a family is brought home from work with abdominal pain by the company nurse. Her mother attempts to give her castor oil but the nurse stops her and tells the parents to call a doctor in case it is appendicitis.
