Amateur and professional bodybuilders prepare for the 1975 Mr. Olympia and Mr. Universe contests as five-time champion Arnold Schwarzenegger defends his Mr. Olympia title against Serge Nubret and the shy young Lou Ferrigno.

This documentary is very much in the style of Pumping Iron, but like Arnold Schwarzenegger's Total Rebuild it is centered around its "Star", Lou Ferrigno. It charts his early years as a kid from Brooklyn, New York who had to deal with having 85% hearing loss due to ear infections in his infancy. He fought against low self esteem by working out with weights in his father's garage, and boy did he win that battle with Mr. Universe (twice), and Mr. World among his physique title wins. Internationally known as a world class bodybuilder and star of The Incredible Hulk, we see him once again step up to the challenge of trying to win the Master's Olympia title in his '40's!

A dishonest businessman asks rich layabout Craig Blake to help him buy a gym, which will be demolished for a development project in Alabama. But after spending time with weightlifter Joe Santo and gym worker Mary Tate Farnsworth, Craig wants out of the deal. The property negotiations turn ugly, causing a brawl at the gym and a spectacle at a big bodybuilding meet, as Craig learns that it's not easy to turn your back on fair-weather friends.
