Teen mystery starring Emma Roberts as the resourceful teen detective. When Nancy leaves her friendly hometown of River Heights for the West Coast and enrols at Hollywood High, her unique personal style immediately sets her apart from her self-absorbed, fast-living peers, especially reigning mean-girl fashionistas Inga (Daniella Monet) and Trish (Kelly Vitz). Their less-than-warm reception might bother the average new girl in town, but not Nancy. She has more important things to think about - namely, a brand new mystery. Even though she promised her worried Dad (Tate Donovan) that she'd quit the 'sleuthing' business, it isn't long before Nancy gets a lead on one of the greatest unsolved cases of all time: the mysterious circumstances surrounding the death of famous actress Dehlia Draycott (Laura Elena Harring).
