Nisa is the villainess in "The Boy who Cried Vamp", one of three segments of the 2006 film Fright Club.
She was played by Maryam Basir.
Nisa is an exotic dancer who Jamal meets at a night club, and later engages in a sexual tryst with him backstage. Unbeknownst to Jamal, Nisa is a vampiress, and not only that, the club is overrun with vampires led by the club's owner, Lamar. In the midst of their sexual encounter, Nisa sinks her fangs into Jamal, leaving him in the process of becoming a vampire. Once Jamal learns about the vampires, he returns to the club and kills nearly all of them, including Lamar (which prevented him from becoming a vampire) and Jamal's girlfriend Kendra, who fully turned. Jamal ends up arrested and tells his story to the police, who don't believe him. At the end of the segment, the evil Nisa remains on the loose.
