Two hippies prance across Italy spreading peace and love while selling naked photos to finance their debauchery. After getting in trouble with the law, they go on the run and end up pulling into a country mansion looking for money. The woman of the house is initially antagonistic, but she soon joins into the swinging 60s fun. That is, until things get all murdery. Despite the title, there is no horror here and, aside from the hedonism, no thrills. The movie is colorful and groovy but the plot feels like an afterthought in which the characters could do any of a thousand things to get themselves out of the predicament they are in but always do the dumbest thing possible. Stupid hippies.
