Shot of the flasks with clear liquid inside; fade into shot of flasks with mass of white mould inside. Fluid is taken from the flasks and put into test tubes. C/Us of test tubes shows how the penicillin drug has cleared deadly germs in one of them. Scientist looks through microscope. Magnified view of "the wonder fungus".
