Jerry Floh ('flea' in German) is invited to a Southampton mansion by influential Buzzy Powers, a guy he knew growing up when his name was Buzzy Pulsky. Jerry has a bad memory of Buzzy and now, twenty-five years later, they have met by chance. Buzzy has risen to success in Hollywood while Jerry grinds out his life as a suburban teacher with a wife, Flo, and three kids. His stay at the mansion, which lasts much longer than the agreed-upon weekend, turns Jerry's world upsidedown from which he barely escapes.
