故事发生在美国西岸的一个小镇中,开发者的到来扰乱了当地居民的平静生活,他们企图将这片人们赖以生存的土地据为己有,对于居民们来说,流离失所的生活似乎在所难免。米奇(西恩·奥斯汀 Sean Astin 饰)和布莱登(乔什·布洛林 Josh Brolin 饰)是一对兄弟,一次偶然中,他们获得了一张年代久远的海盗藏宝图。这一发现让兄弟两人欣喜若狂,因为如果藏宝图所言不假,那么他们就能够守住他们的家园。 在朋友们的帮助下,兄弟两人找到了宝藏的入口,它不在别处,正在福瑞特利家的楼下。让众人感到十分头痛的是,这个福瑞特利家族在小镇上有着远扬的坏名声,当宝藏存在的消息不胫而走后,他们显然已经为了能够将其据为己有而展开了行动。Mikey Walsh and Brandon Walsh are brothers whose family is preparing to move because developers want to build a golf course in the place of their neighborhood -- unless enough money is raised to stop the construction of the golf course, and that's quite doubtful. But when Mikey stumbles upon a treasure map of the famed "One-Eyed" Willy's hidden fortune, Mikey, Brandon, and their friends Lawrence "Chunk" Cohen, Clark "Mouth" Devereaux, Andrea "Andy" Carmichael, Stefanie "Stef" Steinbrenner, and Richard "Data" Wang, calling themselves The Goonies, set out on a quest to find the treasure in hopes of saving their neighborhood. The treasure is in a cavern, but the entrance to the cavern is under the restaurant of evil thief Mama Fratelli and her sons Jake Fratelli, Francis Fratelli, and the severely disfigured Lotney "Sloth" Fratelli. Sloth befriends the Goonies and decides to help them.
