Old-fashioned yarn about a band of adventurous kids who take on the might of a property developing company which plans to destroy their home to build a country club. When the children discover an old pirate map in the attic, they follow it into an underground cavern in search of lost treasure but come up against plenty of dangerous obstacles along the way.
Teenage brothers Michael (Jason Patric) and Sam (Corey Haim) move with their mother (Dianne Wiest) to a small town in northern California. While the younger Sam meets a pair of kindred spirits in geeky comic-book nerds Edward (Corey Feldman) and Alan (Jamison Newlander), the angst-ridden Michael soon falls for Star (Jami Gertz) -- who turns out to be in thrall to David (Kiefer Sutherland), leader of a local gang of vampires. Sam and his new friends must save Michael and Star from the undead.
