A day in Hollywood, 1972, with young people looking for the 24 hours that will change their lives. Zach will open that night for a British rocker at Whisky a Go-Go; he lives in a canyon and plays impromptu duets with a mysterious guitarist he doesn't see. Tammy is a costume designer, open to quick sex with the various rockers she works with and loved from afar by Michael, a photographer recovering from a case of the clap. His good friend is Felix, a morose, alcoholic songwriter. On hand for comic relief is Marty Shapiro, a fast-talking record producer. Getting ready for the gig at the club, Zach's performance, and the early-morning aftermath comprise the film.
