Plot
HairCo. is a megacorporation run by Wallace Eastman that specializes in improving people's hair. His helicopter chases after a scientist named Dr. Harrison who escapes by jumping into a river.
12 years later, a young boy named Adam Harrison the son of Dr. Harrison, lives with his mother, Shelly but keeps getting harassed by the local bullies Tony, Dale, and Garcia for being unjustly judged by other students and being the mutual crush of a kindhearted girl named Emma. Over time, he also notices that strange things start happening to him, like his feet growing bigger so his toes stick out of his shoes and that his hair growing right back over night even after his mother gave it a complete chop.
After discovering not only the fact that his father is alive, but also his current location from a box his mother Shelly had kept hidden, Adam sets out on an epic and daring quest to uncover the mystery behind his long-lost dad only to find out that he is none other than the legendary Bigfoot who has been hiding deep in the forest for years to protect himself and his family from Eastman who is eager to run scientific experiments with his special DNA. What neither of them knew was that a truck driver named Fat Dan had nearly run over Adam. Bigfoot saved Adam, but Fat Dan got some footage of it and put it in the newspaper.
Adam discovers that he too is gifted with superpowers similar to his dad, like having large feet, supersonic hearing, running at incredible speeds and speaking to animals like Tina the red squirrel, Trapper the raccoon, his wife Weecha, Wilbur the Kodiak bear, and Steve the European green woodpecker .
Meanwhile, Eastman heard about the sighting, and although reluctant follows the traces to Bigfoot. In order to draw out Adam, Eastman arranges for his mother's car to be intercepted by a road block agent . The men roam the forest to search for more evidence. After Adam is apprehended, he sends them to a false site, where they fail greatly. This results using Adam as bait to lure Bigfoot, ending with Bigfoot being captured.
Eastman and his scientist Dr. Billingsley begin their experiment on Bigfoot who Eastman recognizes as Dr. Harrison. The hair sample is tested on Dr. Billingsley's usual intern who asks her to sign his volunteer paper. The sample causes the intern to grow extraordinarily long hair all over his body. With the help of the animals, Adam rescues his father, leading to the destruction of the HairCo. facility. Eastman is tranquilized by Shelly as Bigfoot states that he is done with hiding. Dr. Billingsley crawls out of the wreckage as his intern tries to get him to sign his volunteer paper.
Bigfoot returns home and the animals have taken to living with the family. A magazine cover shows that Wallace Eastman has been arrested for his illegal activities. On his way to school, Adam's bullies attempt to haze him again. Having gone on his journey, Adam calmly tells them that he has finally had enough and kindly asks to be left alone. When they refuse to comply, Adam tells his animal friends who scare them into leaving him alone while secretly dismantling their bikes and skateboard to make them crash to further punish them for their previous harassing of Adam which the latter sees and laughs at. Adam dismisses his animal friends as Emma spots the scene and asks about it. Adam asks if she would walk with him to school and she agrees while he begins to explain his life to her.
