Mikey and Brandon Walsh are two brothers whose family is preparing to move due to a new development that is sure to be started unless enough money is raised, which is quite doubtful. But, when Mikey stumbles on a treasure map of the famed "One-Eyed" Willy's hidden fortune, he, his brother, and a few friends set out on a quest to find the riches in hopes to save their homes. The entrance to a cavern is found, but it is located underneath the house of the Fratelli family, a treacherous group of thieves who attempt to beat the "Goonies" to the treasure.
