A Babysitter's Guide to Monster Hunting

Kelly Ferguson, labeled 'Monster Girl' due to a childhood trauma involving a monster attack, struggles with the fear instilled in her. This traumatic experience shaped her life and contributed to her reputation in Rhode Island.

On Halloween night, Kelly plans to attend a senior party, looking forward to a fun night with friends. However, her hopes are dashed when her mother insists that she must babysit Jacob Zellman instead.

Upon arrival, Kelly learns of Jacob's intense fear of monsters, prompting him to show her his drawings that depict these creatures. With empathy and determination, Kelly reassures Jacob that he can overcome his nightmares much like she did.

Just as Kelly begins to ease Jacob's fears, the situation escalates when three tiny monsters, known as Toadies, abduct him. This shocking event transforms Kelly's babysitting job into a rescue mission.

Panicked, Kelly attempts to contact emergency services, but her call fails. In her desperation, she encounters Liz LeRue, a member of a secretive group of babysitters experienced in dealing with supernatural threats.

Kelly and Liz team up to rescue Jacob from the Boogeyman, the mastermind behind the abduction. They realize that time is against them and set off on an urgent mission filled with supernatural dangers.

Liz devises a plan to lure the Toadies using an infant under her care, but her initial attempt fails when the shiny object does not entice them. The stakes are heightened as they strategize for a second chance.

The duo eventually confronts the Boogeyman, who reveals his sinister plan to exploit Jacob's imagination. He plans to use Jacob to amass an army of monsters, strapping him to a device aimed at extracting nightmares.

Kelly and Liz travel to Brown University to enlist help from the Rhode Island Order of Babysitters. There, Liz instructs new trainees on how to combat the monsters and gather information about Jacob's fate.

Using magical dust, Kelly recovers lost memories connected to the Boogeyman from her past. She realizes that she has the ability to manifest her dreams, which becomes crucial for their mission.

The SITs share their experiences with boogeymen, igniting a resolve to create the powerful Angel Hair potion. With Curtis helping to gather the ingredients, they aim to confront the Grand Guignol threat head-on.

As Kelly and Liz set a tracker on a Toadie, they accidentally alert the Boogeyman. This misstep leads them directly to the Halloween party location Kelly initially wanted to attend, complicating their rescue efforts.

In a thrilling showdown, Kelly confronts the Boogeyman after navigating through the chaos of Halloween-themed traps. With cunning, she manages to outsmart the Toadies and leads a determined effort to free Jacob.

With courage, Kelly uses the Angel Hair potion against the Boogeyman, ultimately rescuing Jacob. As Jacob awakens, he disrupts the nightmare creation process, showcasing the power of friendship and bravery.

After Jacob's safe return, Kelly receives praise for her resourcefulness and bravery. Her successful babysitting gig leads to an invitation to return and babysit again, while also catching the eye of her crush.
