Tara, Cal and Sparrow are up against the werewolf Hypnos, who has "bewitched" Manitou to make him reveal the whereabouts of some special rubies that can be strung together to form a necklace they say can make people fall in love. Could such an object really exist? This is the question Cal has on his mind because today is Valentine’s Day and he plans to take advantage of this romantic occasion to get closer to Tara!(Note: This episode being centered on Valentine's day is only present in the English dub, where this episode aired as the first. This is the thirteenth episode in the French version, where the Silent Siren aired as the first.)
