The extraordinary, often bizarre treasures housed in America's museums represent wondrous chapters in history, but a physical display can tell only part of their story. Behind each artefact are amazing tales and secrets to be revealed - tales sometimes brimming with scandal, mystery, murder and intrigue. In `Mysteries at the Museum', presenter Don Wildman visits a wide variety of museums across the United States, taking viewers on a sometimes shocking tour of America's past by re-exmining what's been left behind. Interviews, archival footage and re-enactments bring to life the artefacts' enduring mysteries, some that have never been told before on television.
