The Bloodstained Shadow

Antonio Bido co-writes and directs this Italian giallo horror set in the claustrophobic passages and waterways of the Venetian island of Murano. Upon returning home to visit his brother Paolo (Craig Hill), young professor Stefano (Lino Capolicchio) witnesses a murder one night outside his brother's church. The pair try to dig deeper into the mysterious killings but they are met with threatening letters warning them off unless they want to meet the same fate.

As the body count continues to rise the victims all appear to be from a clandestine group who indulge in secret séances, but who is the culprit?
