An adult cast; the youngest present-day character is twenty-nine. A museum collection of one kind of object; a 1975 weather forecast withdrawn after two men died on a Bridge Street worksite; a failing vial seal and an approaching wind event; a public warning decision; one route with itemized property damage, a shelter opening and an offstage transport worker injury (broken thumb); adult grief, professional guilt and disputed archival consent. No graphic violence and no injury is shown. No character dies during the present events. No hearing, tribunal, inquest, lawsuit, inquiry or romance. The mystery is resolved through stated rules and material evidence.
