Vashista is a sadistic demon who is aligned as a henchwoman for the main villain Mallos (Dominic Keating). The duo were responsible for slaying the wife of Raphael Cain (Lorenzo Lamas) in the 16th century Asia. As a result, Cain vowed to pursue the demons through the centuries to kill them and find his daughter who they kidnapped. Cain became an immortal and was taught magic and samurai swordsmanship. Now in the 21st century, Cain has been reintroduced to Mallos and Vashista, who are gathering power and making life very uncomfortable.
Vashista is involved in a rivalry with Dr. Sara Beckman (April Telek), whom she gets in several catfight like encounters. Vashista is able to use supernatural powers.
Vashista is seen torturning Cain while he is in bondage. In the end, Sara is able to knock Vashista out as Cain is able to kill Mallos by way of a sword. It is assumed that when Mallos died, that Vashista was sent back to hell.
