Based on characters created by Carolyn Keene, Nancy Drew follows Nancy (Emma Roberts) as she accompanies her father Carson (Tate Donovan) to Los Angeles on one of his business trips and stumbles across evidence about a long-unsolved crime involving the mysterious death of a beautiful movie star. Nancy’s resourcefulness and personal responsibility are put to the test when she finds herself in the middle of the fast-living, self-indulgent world of Hollywood.
