An antique map discovered in an attic launches a group of youngsters on a thrilling adventure in pursuit of long-lost treasure, pirates, crooks, and monsters. Along the way they confront the criminal Fratelli family, led by "Mama" (Anne Ramsey), terrorize local bullies and snobs, and save their beloved neighborhood (the Goondocks) from destruction by evil developers.

Mikey Walsh (Sean Astin) is the chief instigator of the Goonies, a tightly-knit alliance of neighborhood misfits: Chunk (Jeff Cohen), Mouth (Corey Feldman), Andi (Kerri Green), Stef (Martha Plimpton), Data (Jonathan Ke Quan), and Brand (Josh Brolin).
