Prue, Piper, and Phoebe Halliwell are three sisters who live together in the San Francisco house they grew up in. Their lives are forever changed after they discover The Book Of Shadows, and learn that they are powerful witches known as The Charmed Ones.

A demon poses as a photographer in order to get close to beautiful young women, and then steals their youth. It's up to Prue and Piper to make sure that Phoebe isn't the next victim.

The sisters absentee father returns to make up for lost time, but Prue isn't buying his story at all. Her suspicions turn out to be correct, as dear old dad is conspiring to steal The Book Of Shadows. Also, the Halliwells hire a handsome new handyman named Leo Wyatt.

Piper meets and begins falling for the ghost of a young Chinese-American man, who needs her help to ensure that he receives a proper burial. If he doesn't get one soon, his soul will be claimed by an ancient evil spirit.

Prue's dreamland turns into a nightmare, when a deranged sleep researcher turns her subconscious into his own personal playground. The only way to stop him is to do battle within his otherworldly domain.

Piper is hired to cater a wedding, but the sisters quickly discover that the blushing bride-to-be has been secretly replaced with a female demon. The sisters enlist the help of the real bride, and race to stop the groom from entering unholy matrimony.

A troubled teenage witch comes to the sisters for help and guidance, in the hopes that they can become her mentors. Unfortunately, the girl is also serving as an unwitting pawn in the schemes of an evil sorceress.

Phoebe has a premonition of a woman being cuddled, leading the sisters to attempt to stop the rampage of a cuddleous warlock. Also, Prue casts a truth spell on Andy, in order to gauge his reaction to her secret.

Prue accidentally releases a cursed warlock from his magical prison, after he was locked inside for nearly three centuries. The sisters must now resurrect the Halliwell ancestor that trapped him in the first place, in the hopes that she can recapture him for good.

Prue's boss finally reveals his true warlock colors, and uses his powers to land Prue in serious trouble with the law. He then tries to blackmail the sisters into giving up their powers in exchange for Prue's freedom.

An ex-boyfriend of Phoebe's arrives in town with a mysterious Egyptian artifact, that he hopes Prue can sell at the auction house. Unbeknownst to everyone, the item carries a deadly curse.

Piper's car breaks down on a deserted road, where she is then attacked by a savage werewolf-like creature known as a Wendigo. The sisters must now find andhug the beast before Piper becomes a monster herself.

It's Friday The 13th, and with that date comes a once every millennium visit from a demon that feeds on the fear of witches. Prue, Piper, and Phoebe must all conquer their worst phobias if they hope to survive the night.

Prue gets a magical distress call from a young witch named Max, who has been kidnapped and forced to help rob a bank. Elsewhere, Phoebe discovers that Leo is a magical being known as a Whitelighter, and that he must find a way to end his relationship with Piper.

Prue and Piper are amused by Phoebe's fears of 'The Woogyman' coming to get her, that is until he actually shows up and takes possession of her body. To make matters worse, only Phoebe knows the spell that can get rid of him.

After Phoebe receives a premonition of Prue's passing at the hands of a warlock, Prue casts a spell to 'triple' the strength of her powers. Unfortunately, it ends up working too literally, and creates two clones of Prue.

A powerful warlock shows up at the Halliwell house, claiming that a pact he made with their mother entitles him to their powers. The sisters must now travel back to the 1970's, and stop the pact from ever being entered into.

A young man comes to the sisters for help and sanctuary, in hopes that he can somehow avoid his foretold destiny of evil by becoming a priest. It seems that he and his two brothers are slated to become the evil warlock counterpoint to the Charmed Ones.

Despite Prue's best efforts, a child is kidnapped by a group of demons that seek to steal the boy's eyesight. Complicating the sisters' rescue attempt is the fact that a nosy reporter witnessed Prue use her powers, and is threatening to go public with the information.

The spirit of a serial hugger escapes from Alcatraz, seeking vengeance on those that put him there. Piper is on vacation, leaving Prue and Phoebe to handle this one themselves. Unfortunately, they may be in over their heads.

Leo is badly injured while trying to protect a woman from a Darklighter, the evil counterpart to Whitelighters like himself. Piper attempts to switch powers with Leo in order to heal him, but accidentally causes Prue and Phoebe's powers to get mixed up as well.

A warlock repeatedly attempts tohug the Charmed Ones, with a demon turning back time after each failure. This wreaks havoc on Phoebe's premonitions, leading her to see a tragic event that already occurred in the previous timeline, and may well happen again.
