Three characters' misadventures in semi-deserted, summertime Rome: a dim-witted mama's boy falls for a tourist; a would-be womanizer struggles to find company for his sex tourism trip to Kraków; a hippie is drawn into his father's schemes to bring him back into polite society.
A masked serial killer with psychosexual issues strangles female coeds with scarves before dismembering them. When a wealthy student identifies one of the scarves and thinks she has a lead on a suspect, she becomes the killer's next target, retreating to her family's remote cliffside villa with three of her girlfriends.
A bickering couple driving cross-country pick up a murderous hitchhiker who threatens to kill them unless they take him to a sanctuary. In return he agrees to split some bank loot he has on him.
