Original title: "Lo Spadaccino Misterioso". Count Ubaldo (played by Gerard Landry) desires to make an unfavorable alliance with the Spanish armies. When Riccardo (played by Frank Latimore) refuses to go along with the plans, he is ambushed in the forest and left for dead. However, he returns with a vengeance, organizes a band of marauders, and begins to pick away at Ubaldo's forces. But Ubaldo kidnaps Laura, and Riccardo must storm the castle to free her. Also stars Tamara Lees, Fiorella Mari, Giulio Battiferri, Enrico Glori, and Antonio Corevi. This was one of a number of low-budget costumers produced by Ottavio Poggi, and now almost impossible to find. Directed by Sergio Grieco. Dubbed in English, with Greek subtitles.
