Ms. Hellfire

When an assassin called Ms. Hellfire sent to kill the Halliwells and all other witches on Friday the 13th is killed, Prue assumes her identity to find out who hired her. Prue soon finds this harder than usual since her boss gives her an ultimatum that she and Jack sell $100,000 worth of goods otherwise they'll be fired. After she is able to continue her investigation, Prue and her sisters have their paths crossed with the demon Barbas. Darryl learns that the sisters are witches.
