Phoebe is picked for jury duty, where a premonition shows her the defendant is innocent. In addition, Paige's sometimes-boyfriend Glen finds the Book of Shadows.
Phoebe is serving jury duty, and when the prosecutor hands her the knife used in the murder, she sees a vision of the murder, and the man on trial, Stan, is not the man she sees. Stan, a magician, attests that the only reason he knew where to find his dead wife was because of a premonition he received. No one believes him, and even Phoebe thinks he is a fraud originally. When the jury goes to reach a vote, she is shot down 11-1. She stalls, calls Leo to help her and is orbed to the mansion where she tells her sisters what is going on. They agree to help her. When Phoebe returns to the courtroom, the rest of the jurors are getting antsy, because they see it as an open-and-shut case. Phoebe tries to explain that just because they don't understand magic doesn't mean they should be afraid of it. They decide to dismiss her, and call in an alternate, but Phoebe says she will prove to them that magic exists. When it doesn't work, she keeps stalling until her sisters come to the courtroom to help her with the Power of Three.
Piper and Leo go to talk to Stan, who tells them more about the premonition. Piper asks who he thinks it is, and he says Andrew Pike. Piper and Leo go to find out more on Andrew, who is the man from Phoebe's premonition, who also happens to be a magician. When Paige and Piper return to get a taped confession, Andrew uses his magic to "disappear," and when downstairs, a rat turns into a demon, and destroys Andrew for giving the confession. The rat follows the Charmed Ones home, trying to get the tape.
When Glen asks to stay at the mansion, Paige says yes. Piper is against this, and when Glen opens the refrigerator and finds potion ingredients, he explores the mansion, going into the attic and finding the Book of Shadows. To prove to him that her sister's are not messing with the occult, Paige does a stretching the imagination spell, but instead it stretches him arm. Thinking it's fun, he stands behind a wall and reaches Pipers leg, letting her know that he knows they are witches. When the rat-demon comes into the house, only Glen is home, and the rat-demon takes him hostage, placing an energy ring around his neck.
Leo comes up with the idea that they should to the rat-demon's leaders and tell them about the tape. He and Paige go, and two of the mice-demons save Glen, and take the taped confession with them. Leo helps by using memory dust on the jury, so the Charmed Ones remain a secret.
Phoebe summons the murder victim, Angela, from the dead, and she tells the jury that her ex-husband is innocent. He has a special gift that he is terrified of: he can see the past and the future. However, he never mastered it. She explains that Andrew was laundering money, and she told, even though Stan told her not to. He was scared, and he killed her. The Charmed Ones tell Stan to be proud of his powers. Leo and Paige go after the rat-demons leaders, and they arrive at the club just in time to save Glen. Paige apologies to Piper in the end, and now understands why keeping their powers secret is so important.
