Serials, more specifically known as Movie serials, Film serials or Chapter plays, were short subjects originally shown in theaters in conjunction with a feature film. They were related to pulp magazine serialized fiction. Also known as "chapter plays", they were extended motion pictures broken into a number of segments called "chapters" or "episodes". Each chapter would be screened at the same theater for one week. The serial would end with a cliffhanger in which the hero and heroine would find themselves in a perilous situation from which there apparently could be no escape. Viewers would have to return in subsequent weeks to see the cliffhangers resolved and to follow the continuing story.
