Holes (1988)

Stanley Yelnats is under a curse. A curse that began with his no-good-dirty-rotten-pig-stealing great-great-grandfather and has since followed generations of Yelnatses. Now Stanley has been unjustly sent to a boys' detention center, Camp Green Lake, where the boys build character by spending all day, every day, digging holes exactly five feet wide and five feet deep. There is no lake at Camp Green Lake. But there are an awful lot of holes. It doesn't take long for Stanley to realize that Camp Green Lake isn't what it seems. Are the boys digging holes because the warden is looking for something? But what could be buried under a dried-up lake? It's up to Stanley to dig up the truth.
