Can we communicate with those waiting for us into the light at the end of the tunnel?

Marc, a recently divorced art restoration expert cannot believe his son when the kid tells him he is having phone conversations with his grandfather, which would be nothing out of the ordinary, except for the fact that his grandfather has been dead for years.

In 1140 AD, a young friar on a secret mission for one of his superiors is chased by an evil entity and will risk his life to protect a mysterious box which he hides within the walls of the Benedictine Monastery of Sant Pere de Rodes, where it will remain hidden for centuries.

In the present time, a mysterious stranger hires Marc to decode the symbols carved on a millenary clay tablet, which will soon put him on the trail of one of mankind's best-kept secrets, the potential existence of a portal to communicate directly with the Other Side.

When the life of his little son is threatened by the evil forces, Marc and his partner Sandra will set off on a dangerous quest that will take them around the country, exploring medieval ruins, unraveling dark family secrets, and fighting for their lives against otherworldly enemies which try to conquer the immense power that lays beyond the portal, a secret hidden for centuries.

Their quest may bring them closer to finding the truth about the portal's existence, but it can also mean the end of his life and that of his loved ones.

Marc will have to determine whether it is a direct line with Heaven, Hell, or with someplace very different.
