An alternate world void of pollution exists, thanks to Martin Energy, a power plant that runs on the strength of women. 'Energy Makers' are highly trained women that can convert their emotions into renewable resources such as electricity, sunshine, and fire. The men in suits that run Martin Energy push the girls to supply energy in amounts that are sure to burn them out. But Susie, the company's star sunshine maker, threatens the imposed order when she learns she can do more than supply sunshine.

Sunshine Susie was a remake of the German film Die Privatsekretärin, and retained many of the originals general characteristics. Renete Muller who starred in the original, was again cast as the country girl seeking fame and fortune in the big city. She takes a secretarial job at a bank, and sets about catching the heart of her boss, Herr Hasel.
