In the throes of a heated moment, two French lesbians, undeterred by their car's confined space, indulge in passionate kisses and gropes. The windows fog up, hiding their exhibitionist tryst from prying eyes, or so they think. Suddenly, firemen, drawn by the steaming windows, approach and catch the women in the act. Shock gives way to excitement as the firemen, unable to resist the allure of the carnal scene, join in, turning the unexpected encounter into a fiery foursome.
