Nancy is an iconic girl detective with a passion for mystery and all things old, but she is about to experience a serious case of culture shock as she heads to Hollywood on an extended business trip with her father, Carson Drew. Having promised him that she has given up sleuthing in favor of becoming a "normal" teenager, Nancy tries her best to resist the lure of the age-old mystery of famous actress Dehlia Draycott's death, and living in Dehlia's old mansion full of clues proves too powerful a force for Nancy to resist.
