Is the Holy Grail a myth or does it really exists? Has it been hidden in Spain? This is what the french anthropologist Philippe Charlier and the shooting team of Scientifilms from Paris wanted to investigate. They decided to follow the steps of the chalice in our country, in a quest for answers. They'll share their discoveries with us in a new episode of the tv series En quête d'ailleurs which will be soon broadcasted on the french-german channel Arte.
