The 16-year-old actress, who rose to fame with her role as Beverly Marsh in the It remake, will be introduced to a younger fan-base with the new movie.

Nancy Drew and the Hidden Staircase, which was produced by Ellen DeGeneres, is set to hit theaters on March 15.

Here is the official synopsis: “After the death of his wife, Carson Drew decides to leave Chicago behind and make a fresh start with his daughter in River Heights. But for 16-year-old Nancy Drew, life in a small town is mighty dull. She longs for excitement, adventure, and the chance to make a difference. Nancy gets that opportunity when she is asked to help solve the ghostly activity at the Twin Elms mansion. Can she help explain the creaking footsteps, exploding lightbulbs and the ominous creature? Is it the handiwork of high-school bully Derek Barnes? Or is it possible that the ghost of original owner Malcolm Colfax is back for revenge? Recruiting her best friends George and Bess, along with local ‘mean girl’ Helen, Nancy Drew is on the case!”
