The plot revolves around a group of young people that take a trip to the ruins in order to film a documentary about Epecuen. Ignoring the warnings, and after a brief tour, they get stranded.
This is a very good film made in 1979s. They really don't make films like this anymore. It is about a 13 an old boy trying to save his brother and himself from the mysterious Tall man that haunts the cemetery as an undertaker.
