The body of young, female DJ Holly Rhodes is found unceremoniously dumped at a construction site. The investigation indicates that she was killed elsewhere and then transported by car. The night of her death, Holly was the DJ for the album release party of aging pop star, Regina Cane, where, it's discovered Regina's party was crashed and she was upstaged by rising pop star, Josie Lang. Castle and Beckett also find Joey, a troubled teen, who was hired by Holly to assist her at DJ parties. They suspect Joey is responsible for thefts that have been occurring at the parties where Holly is the DJ. Castle and Beckett must answer the question of whether Holly was killed by troubled teen Joey or if she became caught up in the competitive drama of aging versus rising pop stars, while Detective Esposito takes Joey under his wing to steer him on the right path before it's too late.
