Henry Smith is a typical man who did not really succeed in his life.He works as a plumber,has no girlfriend & lives with mom in his 50-s.But he had a dream,a dream of recognition & revere...That's why he proclaimed himself to be a 13-century crusader & now assaults random public places,demanding everyone to bow down to him.The only problem is that he knows nothing of who crusaders were for real,but he figures it out on the go using documentary films & middle school knowledge on the subject.
