Taylor Wyatt, a widowed father, is preparing to sell his family home with the help of his sister Liz, a real estate agent. His children are Jack, an adventurous gamer, and Amber, an aspiring artist who frequently draws in her sketchbook. Amber’s drawings are violent and monstrous, causing trouble at school, but the school therapist advises her to continue drawing to channel her anger.

One day, Jack ventures into the woods behind their house and trips, injuring his hand and breaking his phone. He accidentally drops the phone into a nearby pond but retrieves it to find it magically repaired, and his hand’s scrapes have vanished. Intrigued, Jack secretly tests the pond’s powers with other items, which draws Amber’s attention. She follows him into the woods, where her sketchbook—filled with various genocidal monsters—accidentally falls into the pond.

The next day, the family notices strange yellow spots on their window resembling bird droppings. Jack fears these are signs that Amber’s monsters have come to life after their drawings contacted the pond. He tries to explain the pond’s magic to his father, Taylor, who dismisses the idea. Meanwhile, Amber’s monsters begin haunting the town, exhibiting powers consistent with their depictions in her sketchbook. Among these creatures are spiders with arachnid eyeballs called “eyeders,” which steal people’s belongings.

Jack and Amber ride the school bus when they see a truck covered in blue powder blocking the road. Suddenly, a giant blue monster with snake legs and googly eyes, one of Amber’s creations named Dave, emerges from a nearby field and chases the bus. The bus crashes, forcing Jack, Amber, and another kid named Bowman to escape on foot while being attacked by various monsters that were once just sketches.

As the town descends into chaos, the children realize they must track down and capture the creatures before they cause permanent damage. They navigate through the town, encountering multiple monsters, including a dark, hooded figure capable of drawing more creatures, which escalates the mayhem.

Meanwhile, Taylor searches the town, trying to find his children and stop the disaster. He faces the challenge of navigating a town overrun by these phantasmagoric creatures while dealing with his own grief and the urgency to reunite his family.

Jack, Amber, and Bowman use their creativity and resourcefulness to survive the attacks and attempt to contain the monsters. They confront the dark hooded being, which is revealed to be a manifestation of Amber’s deeper fears and grief, capable of creating more chaos through its drawings.

In the climax, the family comes together at the pond. Jack brings their mother’s ashes to the water, hoping to fix everything. Amber retrieves her sketchbook from the pond, and together they confront the monsters. The pond’s magic is harnessed to reverse the chaos, and the creatures are drawn back into the sketchbook or dissolved.

The film ends with the family reunited, having faced their grief and the magical chaos unleashed by Amber’s drawings. The house is ready to be sold, but the family has found a new understanding and connection through the ordeal.

Amber's sketchbook accidentally falls into a strange magical pond behind their house, which causes her drawings—violent, monstrous creatures—to come to life and wreak havoc in the town.

Some creatures include spiders with arachnid eyeballs called 'eyeders' that steal people's belongings, a giant blue monster with snake legs and googly eyes named Dave, and a dark hooded being that can draw more creatures, increasing the chaos.

Jack trips in the woods, breaks his phone, and drops it into the pond. After retrieving it, he notices the phone is magically repaired and his hand's scrapes have vanished, leading him to test the pond's powers further.

Taylor Wyatt is a widowed father preparing to sell the family home. He initially dismisses Jack's warnings about the pond's powers but later races to find his children and navigate the town's crisis to reunite the family and stop the unleashed monsters.

Amber and Jack work together to track down the creatures that have come to life from her sketchbook in order to stop the damage they are causing to the town and prevent further disaster.

• Magical fantasy elements involving a mysterious pond that brings drawings to life, which includes some suspenseful and action scenes with monsters attacking.
