Halloweentown High

Halloweentown High (also known as Halloweentown 3) is a 2004 American fantasy comedy film released as a Disney Channel Original Movie that premiered on Disney Channel on October 8, 2004. It is the third installment in the Halloweentown series. It stars Kimberly J. Brown, Debbie Reynolds, Judith Hoag, and Joey Zimmerman. In the film, Marnie persuades the Halloweentown Council to allow magical students to attend a mortal school, but risks losing her family's powers if something goes wrong before midnight on Halloween. The film attracted over 6 million viewers during its premiere.

Two years after the previous film, Marnie Piper prepares to begin a new school year. She asks the Halloweentown Council to work toward openness between Halloweentown and the mortal world. She proposes bringing a group of Halloweentown students to her own high school in the mortal world. The council is initially apprehensive, mostly due to the legend of the Knights of the Iron Dagger, a fanatical order of knights who wanted to destroy all things magical. However, the council agrees to accept the plan after Marnie mistakenly bets "all the Cromwell magic" that her plan will work. If she does not prove she is right by midnight on Halloween, then her entire family will lose their magical abilities. Marnie, regretting what she said to the council, wants to cancel the program she has made, but her grandmother Aggie opposes, saying that they have nothing to fear.

The Halloweentown students arrive and are magically given human appearances to disguise their true non-human natures. School begins with Marnie acting as a tour guide for the exchange group, claiming they are from Canada. Aggie substitute teaches so she can be available in case of need. Cody, a new student, shows a romantic interest in Marnie.

While Aggie proves unable to teach any subject effectively, the Halloweentown students keep to themselves, hiding in the refuge that Aggie magically creates for them in a remote student locker. Marnie gradually encourages the students to join sports teams, school activities, and to make new friends.

Marnie's progress is interrupted by a warning that appears to be from the Knights of the Iron Dagger, then by a magical incident at the mall that results in the Halloweentown students assuming their natural appearances in public. This is followed by a break-in at the secret magical locker and Cassie's disappearance.

Meanwhile, Marnie's developing relationship with Cody parallels an unexpected romance beginning between Aggie and the school's principal Phil Flanagan. Aggie suspects Cody of being the cause of the trouble and tries to convince Marnie to halt their relationship, but Marnie in turn suspects Flanagan. They eventually discover that Flanagan is the Knight in question; he was told prior to the students' arrival that he was the last of the Order.

Edgar Dalloway, head of the Witches' Council and father of one of the students, is the real root of their problems. He wants to keep Halloweentown isolated from the mortal world, and used Flanagan to ensure that Marnie's project fails. This, he hoped, would cause a negative reaction in Halloweentown and keep the portal between Halloweentown and the mortal world closed.

The Halloweentown students use the school's Halloween carnival to improve mortal attitudes toward magical folk. Their haunted house depicts the ordinary lives of creatures that have typically been seen as monsters in the mortal world, including displays like the "Monster Tea Party" and ogres "picnicking in their natural setting", which winds up boring the carnival goers. Meanwhile, Marnie's mother Gwen uses a Witch's Glass to hunt down Cassie.
