When favourite funnyman Chevy Chase moves in with his fiancee and her mischievous son, he's anything but the "Man Of The House". Life is good for attorney Jack Sturges (Chase). He's engaged to a gorgeous woman (Farrah Fawcett) and is looking forward to a happy new life as a stepfather. But eleven-year-old Ben (Jonathan Taylor Thomas) has other plans for the newcomer. He's determined to scare him off by subjecting him to a hilariously frustrating test of endurance at an Indian summer camp. Calamity and chaos prevail as well as some valuable lifetime lessons about trust and love.
