A witch is preparing a ritual at home when she is interrupted by a man she appears to know, dressed in a rain coat. However she suddenly realizes the meeting is not as friendly as she first thought when he stabs her, obtaining her power to light flames using her fingertips.
At the Halliwell manor, the two older sisters are talking about Piper's job interview tomorrow which has been aided by her boyfriend Jeremy's gift of a bottle of port wine. Prue mentions that she found their old spirit board while she was trying to fix the electricity which had gone out because of the storm.
Inspector Darryl Morris is at Serena's apartment, investigating her murder, when Inspector Andy Trudeau appears and reveals he has been visiting occult shops, following the lead that all the victims are witches who have been stabbed with an athame.
Back at the manor, the cover station has turned and Piper mentions that since Prue wanted a roommate to fill their spare room, Phoebe should come home and live with them. Prue disagrees, saying Phoebe lives in New York, when the door opens revealing the youngest of the Halliwell trio. There is obvious tension between the eldest and youngest of the sisters since Phoebe said "I never touched Roger," although it is clear Prue thinks otherwise.
Later that evening, Piper and Phoebe are sitting in Phoebe's room discussing Prue, mentioning that Prue had to practically sacrifice her childhood to help their grandmother raise them, and yet Phoebe now wants Prue to have a sisterly role in her life rather than a motherly one. They then return downstairs to play with the spirit board, updating each other with their love lives, when the pointer starts moving on its own, spelling out the word "ATTIC".
Prue is skeptical, Piper is freaked out, and Phoebe is intrigued. She goes to the attic and finds the locked door opening itself. She discovers the Book of Shadows and reads an incantation to activate their latent powers. The other sisters come up to the attic and neither are as excited about the possibility of becoming witches as much as Phoebe. She stays awake all night reading about magic and their destiny. They are the Charmed Ones, who have to use their magic to protect innocents against the forces of evil.
Throughout the following day, the sisters discover their individual powers. Prue is annoyed with Roger, her ex-fiance, who is trying to accept full credit for an exhibition which Prue had worked hard for, and ends up with a pen which leaks in his pocket and then explodes in showers of ink when he tries to examine it.
Piper is auditioning for a job as a chef in a restaurant but has not had time to add the port, which will make the recipe, when the interviewer comes in and demands to taste it. She throws her hands up in despair and freezes him. This allows her to add the port and secure the job.
Phoebe meanwhile is riding her bike when she has a premonition of a boy being hit by a truck. To prevent this from happening she swerves in front of the van, and ends up saving the boy.
Jeremy is thrilled Piper has got the job and after their date, he wants to take her to an abandoned warehouse to show her a view of the Bay Bridge. However when they are alone in the elevator, Jeremy reveals his true colors. He is actually a warlock who has grown close to Piper so he can kill the Charmed Ones and obtain their powers. When he tries to attack, Piper freezes him and manages to escape.
Prue, meanwhile, is picking Phoebe up from the hospital when she runs into an old flame, Andy the inspector, and it is revealed that he "checked up" on her.
After talking to Phoebe about her powers, and realizing she can pour milk into her coffee using her mind, Prue thinks this is too much to take and requires some aspirin. They go to the drug store and Phoebe realizes that Prue's power is connected to her anger so she mentions Roger and their father, who abandoned them when they were just little girls. It works, and as Prue's anger grows so do her powers. An entire row of medical products fly off the shelf and Phoebe is triumphant. She tells Prue just to move her headache out of her mind.
When they arrive back at the manor, Piper bursts through the front door, asking Phoebe if she knows how to vanquish a warlock. The sisters concoct a potion and say a spell which causes Jeremy to break out in thorns, but according to Phoebe's premonition, this does not stop Jeremy.
He arrives at their house and the girls realize the only way to vanquish him is to use the inscription on the back of the spirit board, "The Power of Three will set us free" and Jeremy is destroyed.
The next morning, the girls have finally accepted they are not normal but after a conversation with Andy, Prue asks "Do witches even date?" Piper answers, "Not only do they date, but they get the best guys". Realizing that this could be a great opportunity for them, the girls enter the house together and Prue shuts the door with her newly acquired power of telekinesis.
