One of the film's main movie posters featured a long text preamble that read: ''The seven islands of the Hawaiian group are Ohau, Maui, Kauai, Hawaii, Molokai, Lanai, and Niihau. Located in the central Pacific basin, they consistently provide the biggest, most beautiful, and most rideable waves found in the world. Among the surfers who ride these waves are Reno Abellira, Tom Chamberlain, Owl Chapman, Bill Hamilton, Ivo Hanza, Sam Hawke, Barry Kanaiaupuni, Gerry Lopez, Jimmy Lucas, Angie Reno and Jock Sutherland. This film is their story, and that of the fantastic winter and spring of 1972.''
