A projectionist working in a New York City cinema loves the "movie" aspect of his job - he is often doing impersonations of his favorite movie stars in scenes from his favorite movies, and he has movie posters plastered all over his bedroom walls - but he hates his dictatorial boss, Renaldi, who has strict and often unreasonable rules in how he runs the establishment. The projectionist is basically a solitary man, partly due to the nature of his work. As such, he has much time to think about his favorite movies. Sometimes, he fantasizes that he is a character in a movie, a super hero named Captain Flash. In these fantasies, he references many of the movies that he has seen. But the two constants in the fantasies are Captain Flash's battles against his arch enemy, the Bat (who resembles Renaldi), who is portrayed as someone who wants to take over the world much like Adolf Hitler, and Captain Flash saving "the girl", who resembles a real life girl the projectionist admires from afar.
The true story of the mild mannered projectionist, Chuck McCann, who knew in his heart that he was actually CAPTAIN FLASH - The fabled crime fighter.
