Bucky is a five-year-old boy who stopped speaking after the death of his father and who has just moved with his family to a new neighborhood. In an effort to make new friends and find joy building once again, he has to bring a toy gun to the park to join in all the fun and games with the other kids who frequent there. A series of spontaneous events lands the much-desired gun in Bucky's hands, but unbeknownst to him, it's not a toy.
