Phoebe (Alyssa Milano), Paige (Rose McGowan) and Piper (Holly Marie Combs) inadvertently expose themselves as witches in front of Jason (guest star Eric Dane), causing him to leave Phoebe. Richard (guest star Balthazar Getty) casts a spell to free himself of his family's negative karma, but accidentally channels the spirit of Mata Hari, a stripper and double agent during WWI, into Phoebe. Phoebe decides to get revenge on Jason by arranging for a demonic firing squad to kill him. Meanwhile, Piper and Paige try to vanquish a group of Swarm Demons, the last on Chris' list of the most significant threats to Wyatt.
