Her instructor, Professor Didot, promises her a contract on the condition that she receive formal training in Italy for one year.

Faro Black, the chief of the Gypsies, finds out that his son Faro and his girlfriend Egypt have gotten married. Infuriated, he tells that their marriage isn't valid, since Egypt is actually the daughter of wealthy Gordon Lindsay, who is on his way to the gypsy camp to claim her. The two promise to remain faithful to each other, but as time passes and she never hears from Faro, her love turns to bitterness.

This was Theda Bara's third starring film, and the first which she carried all on her own, with no other name actors in the cast. Based on the Alexander Dumas story, The Clemenceau Case involves Iza, a vampire-wife (Bara), whose wicked ways scandalize her husband, Pierre (William E. Shay).

Based -- loosely -- on Leo Tolstoy, this film starred feted stage star Nance O'Neil but is rather better remembered as Theda Bara's follow-up to the sensational A Fool There Was (1914).

The daughter of King Neptune takes on human form to avenge the death of her young sister, who was caught in a fishing net. However, she falls in love with the king, the man she holds responsible.
