Eva is quite happy with her life. It's summer, the weather is nice and she gets along fine with her two best friends Thomas and Jackie. There is just one thing: Her parents won't stop fighting. To scare them, Eva decides to hide for a day. She is sure that by the time she returns, her parents, out of relief, won’t argue anymore. But when Jackie and Thomas go to visit her in her hideout, Eva is gone. When she finally turns up again, she tells her friends a bloodcurdling story about murder, blackmailing and a secret letter.
