High-school principal Dr. Alfred Carroll relates to an audience of parents that marijuana can have devastating effects on teens: a drug supplier entices several restless teens, Mary and Jimmy Lane, sister and brother, and Bill, Mary's boyfriend, into frequenting a reefer house. Gradually, Bill and Jimmy are drawn into smoking dope, which affects their family lives.
