When private eye Doc Sportello's ex-old lady suddenly out of nowhere shows up with a story about her current billionaire land developer boyfriend whom she just happens to be in love with, and a plot by his wife and her boyfriend to kidnap that billionaire and throw him in a loony bin... well, easy for her to say.

It's the tail end of the psychedelic '60s and paranoia is running the day and Doc knows that "love" is another of those words going around at the moment, like "trip" or "groovy," that's being way too overused - except this one usually leads to trouble.
