Where to Watch Streghe verso nord (2001)

Gallio and Teo are two witch defusers. Their task is to track them down and fight them by any means. The second is secretly in love with his sister-in-law Lucilla without knowing that she is a supreme witch. Teo will have to resort to Gallio's teachings (a headbutt, seven steps north and a flash of light to forget everything) to try to render her harmless.
