In a quiet town where every day feels the same, a lonely boy named Tom discovers magic in his own room when his toy Velociraptor, Tim, springs to life. Bound by the rule that Tim can only speak and move when they are completely alone, the two embark on secret adventures, battling imaginary dragons and building pillow fort castles. With the dinosaur's witty encouragement, Tom finds the confidence to overcome his shyness and make new friends at school, realizing that while their connection must remain hidden, Tim's bravery will always be a part of him.
