His music practice room in the Abbey of Sant' Anselmo in Rome is sound-insulated, just to be on the safe side. "There's nothing nicer after a 16-hour working day than to get out the electric guitar for a quarter-of-an-hour," says Abbot Primate Notker Wolf. He's the head of the Order of Saint Benedict, with its 8,000 monks and 16,000 nuns worldwide. And he's a rock-music fan.

Whenever he has time, he goes on stage with his band "Feedback" in his black habit with his pectoral cross and his electric guitar. An unusual hobby for such a high dignitary of the Roman Church. "You need a degree of freedom," says Notker Wolf, who finds the internal church debates about this or that papal dispensation sometimes rather irrelevant to ordinary life. He thinks the cares and problems of the people he meets around the world are more important than theological disputes. The 64-year-old abbot covers 200,000 air-miles a year visiting the order's houses worldwide. "I just hope," he says, "that all the delays and waiting times are refunded in Purgatory."

Born in the foothills of the Alps in southern Germany, Notker Wolf knows the problems of the world's poor countries in detail. He speaks 13 languages. Before his election as Abbot Primate, he was Arch-Abbot of the Missionary Benedictines in St. Ottilien, and even then responsible for 20 monasteries with a total of 1,100 monks in Asia, South America and Africa. For the last four years he has been Abbot Primate, and thus head of the Benedictine Order. He resides at one of the best addresses in Rome: Sant' Anselmo on the Aventine Hill. So, hierarchically speaking, he's right at the top. But he doesn't like titles, or careerist attitudes. This is his link with the 1960s student rebels, he says: the anti-establishment protest. He thinks the gospel is also anti-institutional at heart, and that's also what he likes about rock music.

This film is a portrait of the witty and unpretentious Abbot Primate of the Benedictines.
