Girl vs. Monster

Skylar, a fearless 15-year-old with a powerhouse voice, gears up for the Halloween Bash with Henry and Sadie. They finalize the plan for Skylar to sing on stage with Ryan Dean. The mood is electric as they prepare for a night that could change Skylar's future.

The day after the party, Skylar's parents insist she stays inside, locking the doors and activating an alarm that shuts out the world. The home turns from sanctuary to cage as fear tightens its grip on the family. Skylar realizes she may not be free to follow her dreams without confronting the danger outside.

When Skylar tries to cut the power to slip out, a hidden terror is released: Deimata, a monster sealed in her parents' containment unit. Deimata feeds on fear and quickly begins to seize control of the house. The atmosphere shifts from routine to peril in an instant.

A shocking family secret reveals Skylar is the fifth generation of monster hunters. The revelation reframes the danger as a legacy she must embrace. She understands that fear, not strength alone, is the real foe they must face.

Skylar, Sadie, and Henry rally with the family's monster-hunting gear to confront Deimata during the impending party at McQuarry Mansion. They steel themselves for a night of battles against fear itself. Skylar's voice becomes their key weapon against the monster.

Early in the night, Henry is frozen by his own monster, immobile with fear. Cobb, the trusted assistant, carries him back toward safety to recover and regroup. The team loses a crucial ally at a critical moment.

Deimata uses a cruel ruse to lure Skylar's parents—Julie and Steve Lewis—into a trap by pretending Skylar is in danger. The plan pulls them away from safety, intensifying Skylar's stakes. The family must confront the threat while divided.

Myra, Skylar's rival, is momentarily possessed by Deimata and heads toward the party to challenge Skylar's confidence. The possession sets up a tense, public confrontation. Sadie steels herself to stand by Skylar and support her friend.

At the party, Deimata fully possesses Myra and taunts Skylar about her nerves about singing. Skylar and Sadie brace themselves as fear threatens to derail the performance. The haunting display reveals the true reach of Deimata's influence.

Skylar and Sadie realize Deimata's power to possess people and push to rescue those trapped upstairs. They rally their friends to push back against the mental assaults and reclaim the house. Trust among the trio deepens as they confront the monster's manipulation.

Henry returns with crucial news just as the plan shifts toward a final push. He joins Skylar and Sadie at the mansion to coordinate a rescue and the next confrontation. The group steels themselves for the most dangerous phase of the night.

Skylar grabs the microphone and takes the stage with Ryan's guitar backing. Her performance is fearless, and the courage drains Deimata's power as the crowd cheers. The fear that fueled the monster begins to wane as Skylar connects with the audience.

Deimata reappears and seizes Skylar's parents, testing their faith in her. Skylar, Sadie, and Henry race to reach them, supported by their friends along the way. The trio's trust becomes the instrument that weakens Deimata's hold.

The trio's courage and the parents' belief finally defeat Deimata, sending the monster retreating. Balance returns to the house and the night shifts from danger to celebration. The group realizes their bond has grown stronger through fear and action.

In the night’s aftermath, Henry and Sadie shed their fears, while Skylar, Ryan, and Myra end the night with a song in Ryan's basement. Myra's reluctant alliance deepens into friendship as they toast their hard-won unity. The night closes with music, camaraderie, and the sense they can face any monster together.
