This film follows two men, the plain Herkules (Ib Schønberg) and the rich Erik (Angelo Bruun). When they were boys, Erik defended his good friend Herkules. And he never forgot that fact. They stay up for each other, no matter that Erik gambles his money away, or what ever happens to Herkules. Great story, but I feel that the movie only survives because of Ib Schønbergs powerful performance as the plain man, fighting for simple justice, defending the little man. "Plat eller krone" means heads or tails, in the meaning of flipping a coin, which Erik does a lot in this movie.
