Hosted by Robert Stack, the show documents a handful of unsolved cases in each episode. These are true stories of unsolved crimes, missing persons, unexplained phenomena, wanted fugitives and unresolved investigations "relevant at the time of the original air dates". A compelling mystery is outlined by the host with supporting accounts from law enforcement, witnesses and family members surrounding the event in question. The audience is asked to call a tip line with any information that may help shed new light on these open-ended cases. Later episodes often include a brief update to a prior mystery. Updates typically include details leading up to the resolution of a previous "unsolved mystery." Occasionally, an update is broadcast with additional facts acquired since original air date.
