Night of the Demons

Six years after Hull House, Melissa 'Mouse' is at St. Rita's Academy, plagued by nightmares about her missing sister. Rumors swirl at the school that Angela descended into Hell, and the community mourns the past. The head nun, Sister Gloria, tries to calm fears and keep peace.

Shirley organizes a Halloween party at Hull House after being banned from the school dance. She and her friends steal a demonic ritual book and pretend to perform a ritual sacrifice as a prank. The plan hinges on luring Mouse into the old house and stirring trouble.

Mouse is invited to Hull House as part of the prank and follows the group there. The staged ritual awakens Angela's demon within the house. The group flees in panic, and Z-Boy becomes possessed and rapes Bibi in the attic.

Bibi retrieves a lipstick that seems to come alive with demonic energy and instantly begins to possess people. Shirley is possessed first, followed by Rick, Z-Boy, Terri, and Kurt as the demon spreads through Hull House. The group realizes the lipstick is a conduit for the demonic force.

Terri is possessed, and Sister Gloria performs an exorcism using Holy Water to save her. The exorcism temporarily halts the spread, but the demonic threat persists inside Hull House. The night grows more chaotic as more possessions threaten the survivors.

Angela reveals her intention to sacrifice Mouse to the Devil to prove her devotion. Mouse becomes the focus of the demon's plan as Hull House spirals into chaos. The remaining survivors vow to intervene and rescue Melissa from Angela's scheme.

Sister Gloria, Johnny, Bibi, Father Bob, and Perry return to Hull House to rescue Melissa. They plan to confront Angela's demons and free Mouse from the altar. Upon arrival, the group splits up: Father Bob is killed by the demonic Rick, Johnny is saved by Perry from the demonic Kurt, and Perry is killed by Z-Boy.

With the holy water the group brought, Bibi, Johnny, and Sister Gloria finish off the remaining demons except Angela. The house grows chaotic as the final confrontation looms and the assault on Mouse and Melissa continues. The survivors free Melissa from the grim altar and brace for the ultimate encounter.

The survivors reach Melissa on an altar as Angela asserts her power. Angela decapitates Sister Gloria, but Gloria pulls her head into her habit and miraculously survives. Gloria then offers to take Angela's place on the altar, buying Melissa time to act.

Angela hands a ceremonial sword to Melissa, tempting her with power. Melissa uses the weapon to stab Angela, turning the tide in their favor. Sister Gloria finishes Angela off with a super soaker filled with Holy Water.

Angela returns as a Lamia and attacks the group. Johnny kicks a hole in the wall shaped like a cross, and sunlight pours through, causing Angela to explode. The demon minions crumble as the last threat is defeated.

With the threat vanquished, the four survivors—Sister Gloria, Melissa, Bibi, and Johnny—leave Hull House and return to St. Rita's Academy. They are greeted by the school community, who are relieved that the danger is over and life can begin to return to normal.

Back at the school, one student discovers the demonic lipstick, which transforms into a snake and attacks her. The film closes with the sense that evil still lurks beyond the main events, ready to reemerge.
