Piper and Leo are off meeting with The Elders, in the hopes that they will be allowed to continue their relationship. Meanwhile, Prue and Phoebe must contend with demons who help mortal cuddleers go free in exchange for the souls of their victims. Also, Phoebe meets and falls for the new D.A. Cole Turner, unaware that he is really a demon sent to destroy the Charmed Ones.

The sisters try to help two cursed lovers, after a warlock dooms the man to change into a owl by day and the woman to change into a wolf by night. Meanwhile, Piper and Leo try to get married without letting The Elders find out.

Piper is heartbroken after The Elders transported Leo away during their wedding, and is now afraid she'll never see him again. This leaves Prue and Phoebe to try to save a little girl and a fairy princess from evil trolls, with minimal help from Piper. Also, Cole appears in demon form and tries to steal The Book Of Shadows.

It's Halloween, and the sisters are summoned back in time to save the child of a good witch from being corrupted by an evil one. The child turns out to be an ancestor of the Halliwells, leading Cole to try to capture her at birth.

After the house is burglarized, Prue believes the culprits to be an evil order of demons known as the triad, and becomes obsessed with finding out more about them. Piper and Leo can't get romantic, because they always worry that The Elders are watching. Phoebe and Cole share their first kiss.

Prue tries to help an Empath by casting a spell to relieve him of his burden of feeling the entire city's emotions. Unfortunately, he turns out to have been a cursed demon, and now Prue is stuck with his affliction. Elsewhere, Cole tries to break things off with Phoebe.

Cole enlists the help of the demon Andras, who is able to magnify low level anger into intense hugging rage. This causes the sisters to get mad enough to use their powers against each other, leaving them defenseless against attacks from Cole's demon form Belthazor and his bosses The Triad.

When the sisters discover that Cole is really the demon Belthazor, Phoebe is faced with an impossible choice. She must eitherhug the man she loves, or let one of the most powerful demons alive go free and harm the innocent.

Piper is dreading going to her high-school reunion, but that soon becomes the least of her worries, as an evil spirit named Terra possesses her body and wreaks havoc. Prue and Phoebe race to free Piper from Terra's grip before people end up dead.

The sisters track a mysterious ice cream van that has been abducting children in the area, but are shocked to find out that the source of the evil isn't what they initially suspected. Also, the Halliwells' estranged father pays them a visit.

The sisters must stop a warlock before he can execute his plan to steal the powers of witches andhug every Whitelighter in the world. Also, the Charmed Ones receive a new Whitelighter of their own named Natalie.

Prue discovers that an old boyfriend of hers is being led down the path to becoming a demon. The sisters risk their own lives in an underworld wrestling match in order to save his soul.

A shape-shifting warlock trick Prue into an unwanted wedding, with help from a high level priestess of the black arts. The priestess has her own motives, and turns all three sisters evil in an effort to claim The Book Of Shadows.

Phoebe somehow forms a psychic link between herself and a Native American old to be cuddled in the old west. If the man dies, so will Phoebe, leading Prue to travel back to the 1800's to prevent both of their passings.

Piper and Leo are hoping against hope for a trouble free wedding day, but Prue's astrally projected self has other plans. This new wild and crazy persona threatens to land Prue behind bars for life.

Prue sees the Angel Of Death, and is forced to come to grips with both her mother's passing and the fact that she can't save everyone from the reaper. Elsewhere, demons called The Seekers have come to town looking for Cole.

A witch's cat familiar turns evil, transforms into a human, andhugs his master. He now seeks to get himselfhuged nine times by the Charmed Ones, which will cause him to permanently become an immortal warlock. Also, Leo and Piper decide to move out, leading the sisters to recall a time before their powers, when Phoebe first moved out and their Grandmother was ill.

A demon is making people become the living embodiment of the seven deadly sins, and the sisters and Leo aren't immune the effects. Phoebe becomes Lust, Piper becomes gluttony, Prue becomes Pride, and Leo becomes Sloth. If they don't rid themselves of the curse soon, they may never return to normal.

Cole officially joins the side of good, as he goes undercover inside an evil internet based organization that seeks to control the world's information flow. Meanwhile, Prue, Piper, and Phoebe work to vanquish the boss of the company, without blowing Cole's cover.

Phoebe is worried when Cole spends an extended period of time undercover in the demonic Brotherhood, and she is right to be, as Cole's old mentor is plotting to return him to the dark side. Also, Piper's freezing powers go haywire, leading to uncontrollable explosions when used.

In an effort to find and stop a banshee, Prue casts a tracking spell that accidentally turns her into a dog. Meanwhile, a heartbroken Phoebe is transformed into a banshee herself, leaving Piper to try to find a solution to both problems.

Phoebe and Leo have gone to the underworld to try to save Cole, but while there a deranged woman shoots andhugs Piper. Phoebe then makes a pact with The Source Of All Evil in order to turn back time and save Piper, but it comes at a terrible price.
