Beyond the Line – Stories Carved in Rock follows a group of speleologists exploring the Cavallone Cave, a place that holds numerous traces of the past, including inscriptions left by refugees during World War II. The documentary retraces the history of that period through the testimonies of those who lived through those events, including an elderly man who also built the cableway that today allows access to the cave. A journey between past and present, where the memory of those historical moments resurfaces through the rock and the voices of those who helped write this chapter of history.
