When Billy finds himself in a haunted house, the mysterious owner grants him one wish - the Midas Touch.
The movie also goes by an alternate name Kid Midas, and was released in 1997.
He soon learns that it is more of a curse than a blessing when he turns his grandma into gold, which later got stolen and got melted by Cora, the local pawnshop owner. Eventually, Billy defeated Cora with the Midas Touch and turning her into gold.
At the end of the movie the Midas Touch is taken from Billy, turning everything and everyone back to normal.
