Jessica and Elizabeth Wakefield are looking forward to another summer as interns at the Sweet Valley News. Elizabeth can't wait to get to work as a reporter; Jessica can't wait to spend time with the gorgeous new editor. Jessica is even more excited when she discovers that a crossed telephone line allows her to eavesdrop on other people's conversations. She loves listening in on the private lives of Sweet Valley - until she overhears plans for a murder!

Elizabeth thinks Jessica's imagination is working overtime, until the body of a teenage girl washes up on the beach. The police make a connection between the girl and a local drug ring - and Jessica makes the connection between the voice on the phone and someone who works in the newspaper office! When the twins start to get threatening calls at home, it's time to put the killer's plans on hold before he disconnects them forever!
