The Wizard

Jimmy Woods is a young boy who has suffered from an unnamed, but serious mental disorder ever since his twin sister Jennifer drowned in the Green River two years earlier. He does not interact with anyone, spending most of his time building things out of blocks or boxes, and he always carries his lunch box with him. He is determined to go to "California", at first nearly the only word he can say since the tragedy. The trauma of the drowning and Jimmy's condition have broken up his family; he lives with his mother Christine Bateman and stepfather, while his brothers Corey and Nick live with their father Sam. When Jimmy is put into an institution, Corey breaks him out and runs away with him to California. Christine and her husband hire Putnam, a greedy and sleazy runaway-child bounty hunter, to bring back only Jimmy; he competes with Sam and Nick to find the boys, and both groups sabotage each other's efforts, resulting in chaotic confrontations.
Along the way, Corey and Jimmy meet a girl named Haley Brooks, who is on her way home to Reno. After discovering that Jimmy has an innate skill for playing video games, Haley (who nicknames him "the Wizard") tells them about "Video Armageddon", a video-game tournament with a $50,000 cash prize. She then agrees to help the two reach Los Angeles to participate for a cut of the money. By doing so, they hope to prove that Jimmy does not need to live in an institution. The trio hitchhike across the country, using Jimmy's skill and appearance to hustle people out of their money by playing video games. Along the way, they encounter Lucas Barton, a popular preteen big shot who owns a Power Glove and shows his skills at Rad Racer, declaring he is also entering the tournament.
They finally arrive in Reno, where it is revealed that Haley wants her share of the prize money to help her father buy a house. With the help of an acquaintance trucker, Spanky, they use money won at the craps tables to train Jimmy on several games in the Reno arcades, using Nintendo PlayChoice-10 machines. After a difficult search, Putnam catches up with the trio, capturing and losing Jimmy twice. At the tournament, which is held at Universal Studios Hollywood located in Spartacus Square, Jimmy qualifies as a finalist after a preliminary round of Ninja Gaiden. In between rounds, Putnam chases the kids through the park and almost causes Jimmy to miss the final round. The Woodses, the Batemans, and Putnam convene in the crowd as Jimmy competes with Lucas and another finalist in a game of Super Mario Bros. 3, which at the time had not been released in the United States. Jimmy wins the tournament at the last second after finding a Warp Whistle and getting the star, thereby winning $50,000.
On their way home, the family passes by the Cabazon Dinosaurs, a tourist trap, and Jimmy becomes so excited and restless that they pull over. He runs from the car up into one of the dinosaurs, his family in pursuit. Inside, Jimmy takes from his lunchbox one of his pictures of Jennifer, taken at the foot of the dinosaur with the rest of the family during a vacation, and Corey realizes that he simply wanted to leave his sister's mementos in a place where she would be happy. He leaves the lunchbox inside the dinosaur and, at Christine's request, Sam drives the boys and Haley home. Haley kisses Jimmy and Corey after which Jimmy kisses Haley on her cheek.
