Cliffhangers is an American drama television series that aired on NBC from February 27 to May 1, 1979. It attempted to revive the genre of movie serials in a television format. Each hour-long episode was divided into three 20-minute segments, a mystery Stop Susan Williams, a science fiction/western hybrid The Secret Empire and a horror story, The Curse of Dracula.

A serial film, film serial, movie serial, or chapter play, is a motion picture form popular during the first half of the 20th century, consisting of a series of short subjects exhibited in consecutive order at one theater, generally advancing weekly, until the series is completed. Usually, each serial involves a single set of characters, protagonistic and antagonistic, involved in a single story, which has been edited into chapters after the fashion of serial fiction and the episodes cannot be shown out of order or as a single or a random collection of short subjects.
