Say No to Strangers was developed for 1st and 2nd grade children so it is simple and not frightening like many other films of the same genre. In the film, children learn safety rules at school and must apply them to situations as they arise in the real world. A group of kids talk to a man who is trying to interest them in his dog, but the kids walk away. Later, they don’t comply when a woman tries to get them to get into her car, and they avoid a dark alleyway. The film also makes the frequent point that policemen are there to help kids, "Remember, the policeman always is your friend." After their adventures, the kids make posters of the rules they learned.
