The Minus Man

A cold-blooded serial killer floats around the country and chooses his victims from people who complain about their lives and indicate a willingness to be killed. His murders are introduced with the killing of an asthmatic junkie. The killer settles into a seaside rooming house run by an unhappy married couple and waits for his next victims to unveil themselves. Dream cops plague his nights, while plotting his murders. Meanwhile, he also starts a relationship with a postal clerk, which momentarily misleads one into thinking he is ready to give up his murderous life. —IMDb
